How are organisms able to generate ATP without oxygen?

Answers

Answer 1

Answer:

Without oxygen, organisms can split glucose into just two molecules of pyruvate. This releases only enough energy to make two ATP molecules. ... This releases enough energy to produce up to 38 ATP molecules. Thus, aerobic respiration releases much more energy than anaerobic respiration.

Derived characters are only shared with the most recent common ancestor of a clade, whereas____characters are shared with the most recent common ancestor as well as earlier ancestors.

Answers

Derived characters are shared only with the most recent common ancestor of a clade; while reversed or primitive characters are shared with the most recent common ancestor and earlier ancestors as well.

Reversed or primitive characters are characters that are present in a group of organisms that are more distant relatives and are also present in the common ancestor of that group. These characters are typically found in organisms that have diverged from a common ancestor some time ago and have been retained through evolutionary history. On the other hand, derived characters are unique to a specific group of organisms and are not found in their ancestors, they are typically new characteristics that evolved in the most recent common ancestor of a clade.

Answers

The protein indicated by a question mark in the figure depicting the steps of the common pathway of coagulation is thrombin.

When coupled to thrombomodulin, thrombin activates Protein C, a coagulation cascade inhibitor. After thrombin binds to thrombomodulin, a key membrane protein produced by endothelial cells, protein C activation is significantly increased. Factors Va and VIIIa are rendered inactive by activated protein C. Protein S's activity is somewhat increased when active protein C interacts to it. Antithrombin, a serine protease inhibitor, also renders thrombin inactive.

Materials are returned to the blood from the filtrate by which of the following processes?
A. filtration
B. selective reabsorption
C. excretion
D. secretion

Answers

Selective reabsorption is the method through which components from the filtrate are transferred back into circulation. The correct answer is (B).

In the renal tubules of the kidneys, selective reabsorption takes place when urine is formed. The first stage of filtering takes place in the renal corpuscle, where blood is filtered into the renal tubules through the glomerular filtration barrier. As a consequence, a filtrate made up of water, ions, nutrients, and waste products is created.

Not every component in the filtrate, though, is a waste product that must be removed from the body. In order to sustain homeostasis, certain molecules, including glucose, amino acids, vitamins, and certain ions, must be reabsorbed into the circulation. Active or passive transport of these beneficial compounds from the filtrate in the renal tubules back into the peritubular capillaries surrounding the tubules is involved in selective reabsorption. This procedure aids in preserving vital chemicals and preventing the loss of urine.

Which of the following causes Earth's seasons? a) the tilt of the earth on its side b) oceans currents c) the earth's orbit d) The distance of the earth from the sun

Answers

The plant-herbivore interaction described in the question would best be described as mutualism, as the grass benefits from being grazed by the herbivore. The tilt of the earth on its side causes Earth's seasons.

The tilt of the earth on its axis plays a major role in causing Earth's seasons. The earth's axis is tilted by an angle of 23.5° in relation to the plane of its orbit around the sun. This tilt causes the hemisphere of the earth that is tilted towards the sun to receive more direct sunlight than the hemisphere that is tilted away from the sun. This differential in the amount of sunlight received by each hemisphere causes the seasons. During the summer months, the northern hemisphere is tilted towards the sun and receives more direct sunlight, while the southern hemisphere is tilted away and receives less direct sunlight.

would a superstorm form over rocky mountains?

Answers

It is unlikely for a superstorm to form directly over the Rocky Mountains, as superstorms are typically associated with low-pressure systems that develop over warm ocean waters. However, the Rockies can play a role in influencing the formation and behavior of weather systems.

As air moves over the Rockies, it can be forced to rise and cool, leading to the development of clouds and precipitation. This can contribute to the formation of weather systems, which may then move on to develop into larger storms as they interact with other atmospheric conditions.

Furthermore, the Rockies can act as a barrier, causing air masses to be diverted and influencing the formation and movement of weather patterns. This can lead to the development of strong winds, thunderstorms, and other forms of severe weather in regions surrounding the Rockies.

Overall, while superstorms may not form directly over the Rockies, the region can still play a significant role in shaping weather patterns and influencing the development of storms and other forms of severe weather.

Answers

If crossing over occurred at the point indicated,  the genotypes of the resulting chromosomes is "You can't tell; the alleles aren't labeled on the chromatids that are crossing over."

Because the alleles are not marked on the chromatids that are crossing over at the point shown, it is hard to tell the genotypes of the resulting chromosomes.

A phenotype is a trait that can be seen in an organism, and a genotype is the set of genes that make up an organism. Genotypes of different organisms are different, and they are responsible for different physical and biological traits in an organism.

Genotypes are often used in the study of genetics to figure out how likely it is that certain traits or characteristics will be passed down from parent to child.

During meiosis, a process called "crossing over" takes place. This is when genetic material from homologous chromosomes is swapped.

The genetic material in the cells that come out of this process is different in each of them.

Therefore, the correct answer is "You can't tell; the alleles aren't labeled on the chromatids that are crossing over."

What is the super additive effect of Multisensory integration?

Answers

The super additive effect of multisensory integration refers to the phenomenon where the combined influence of multiple sensory inputs results in a greater impact on perception, cognition, or behavior than the sum of their individual effects.

In other words, when our brain processes information from multiple sensory sources simultaneously, it can lead to enhanced performance and a more robust understanding of our environment. Multisensory integration is the process through which our brain combines and integrates information from different sensory modalities, such as sight, sound, touch, taste, and smell. This integration enables us to perceive the world more accurately and efficiently, as it helps our brain to create a coherent and unified representation of external stimuli.

To illustrate the super additive effect of multisensory integration, consider a scenario where you are trying to locate a source of sound in a noisy environment. If you were to rely solely on auditory information, it might be challenging to pinpoint the exact location of the sound. However, if you also have visual cues, such as a person talking or a flashing light, the combined sensory inputs can help you determine the sound's source more accurately and quickly. This enhancement in performance can be explained by the fact that the brain is better equipped to process and interpret information when it receives input from multiple senses.

As a result, the super additive effect of multisensory integration allows us to better perceive, interpret, and respond to our surroundings, ultimately improving our ability to navigate and interact with the world around us.

Both embryonic stem cells and iPS cells can possibly be used for therapeutic treatments heart, brain and other differentiated cells can grow from them.

Pluripotent stem cells called embryonic stem cells (ESCs) are produced from the inner cell mass of a blastocyst, a preimplantation embryo in its early stages. Four to five days after fertilization, human embryos reach the blastocyst stage, consisting of 50 to 150 cells. The blastocyst is destroyed when the inner cell mass (embryoblast) is isolated by immunosurgery, which raises moral questions about whether or not pre-implantation embryos are subject to the same moral standards as those that are developed after implantation.

In the realm of regenerative medicine, pluripotent stem cells show promise. They serve as a single source of cells that can be used to replenish those lost due to damage or illness since they can multiply endlessly and give rise to every other type of cell in the body (including neurons, heart, pancreas, and liver cells).

The muscle group responsible for anchoring the pelvis when lying supine (on your back) is the gluteus maximus muscle.

The gluteus maximus is the largest muscle in the buttock region and is responsible for the movement of the hip and thigh, as well as stabilizing the pelvis during movement. When lying on your back, the gluteus maximus contracts isometrically to maintain the position of the pelvis and prevent it from rotating or tilting.

The gluteus maximus also works in conjunction with other muscles such as the hip flexors and abdominal muscles to maintain a stable pelvis during movement. Strengthening the gluteus maximus through exercises such as squats, lunges, and hip thrusts can help improve pelvic stability and prevent injury during activities such as running and jumping.

In red blood cells, lactate is continually produced as a consequence of their anaerobic metabolism. What is the energetic cost (to the liver) in ATP of converting this lactate back to glucose, per molecule of glucose generated?

Answers

The energetic cost of converting lactate back to glucose per molecule of glucose generated is 6 ATPs.

Lactate is produced by anaerobic respiration in muscles when oxygen demand exceeds supply, causing fatigue. The liver converts the lactate back to glucose, which muscles can utilize for further energy production. There are two main pathways that produce ATP in human cells: aerobic respiration (requiring oxygen) and anaerobic respiration (not requiring oxygen).

During anaerobic respiration, energy is obtained from glucose without the use of oxygen. As a result of anaerobic metabolism, red blood cells generate lactate. Red blood cells are the only mammalian cells that lack mitochondria and consequently depend solely on anaerobic metabolism for energy production. This reliance on anaerobic metabolism has significant consequences, with lactate being continually produced as a byproduct.

The liver is responsible for converting lactate back to glucose in a process known as gluconeogenesis. It is an ATP-intensive process that consumes 6 ATP molecules per molecule of glucose generated, according to research.
