Does the net gain of atp in glycolysis differ when glycogen, rather than glucose, is the starting material? what is the change?.
Answers
The energy is greater and producing a net gain of ATP in glycolysis of 3 ATP.
What is glycolysis?The metabolic process known as glycolysis turns the sugar glucose (C6H12O6) into pyruvate (CH3COCO2H). The high-energy molecules adenosine triphosphate (ATP) and reduced nicotinamide adenine dinucleotide are created using the free energy released during this process (NADH). A series of ten enzyme-catalyzed processes make up glycolysis. binding energy of carbs is captured. Retention of ATP One metabolic route that doesn't require oxygen is glycolysis (In anaerobic conditions pyruvate is converted to lactic acid)Glycolysis occurs frequently in various species, which suggests that it is an old metabolic route. In fact, the events that make up glycolysis and its companion process, the pentose phosphate pathway, take place in the oxygen-free environment of the Archean oceans, also in the absence of enzymes, and are catalyzed by metal.To learn more about glycolysis with the given link

thioesters can release more energy upon hydrolysis than regular esters. explain in 2-3 sentences.
Answers
Thioesters can release more energy upon hydrolysis than regular esters because the sulfur atom in thioesters is more polarizable than the oxygen atom in regular esters, allowing for greater stabilization of the leaving group during hydrolysis.
This results in a more favorable and exothermic reaction, releasing more energy. Thioesters can release more energy upon hydrolysis than regular esters due to the difference in bond strength between the thioester bond and the ester bond. The thioester bond is weaker than the ester bond, which means it requires less energy to break, resulting in a more exergonic hydrolysis reaction and release of more energy.
Additionally, the sulfur atom in the thioester bond can stabilize the leaving group, making the reaction more favorable.

What causes DNA to twist in to a twisted ladder or a double helix?.
Answers
The DNA backbone, which alternates deoxyribose and phosphate strands, causes the DNA to twist into a double helix or twisted ladder shape.
The DNA's backbone is made up of alternating phosphate and deoxyribose strands. Due to the joining of two strands, it bends. Due of DNA's spatial need, this happens. Histones, a protein, enable it to coil and supercoil. The GC bond possesses three hydrogen bonds, compared to the AT bond's two. More DNA couldn't be present in the nucleus if it uncoil and unfolded. DNA stability is provided by the twisted motif. As a result, it has a twisted shape.

A. Most of the confirmed hypotheses were found to be fabricated
B. Dr. Gall announced that his research was done incorrectly
C. Scientists were worried that the experiments would encourage racism
D. The descriptions within the observations were not testable and objective
Answers
Most of the confirmed hypotheses found to be fabricated were the phrenological studies conducted by Dr. Franz Joseph Gall discredited in the nineteenth century. Phrenology was a popular pseudomedicine in the late 19th century that posited measurements and other characteristics of the human skull determined different aspects of a person's actions and personality.
Answer A is correct.
Phrenology was mostly discredited as a scientific theory by the 1840s. This was due only in part to a growing amount of evidence against phrenology. Phrenologists had never been able to agree on the most basic mental organ numbers, going from 27 to over 40, and had difficulty locating the mental organs.
Gall believed that bumps on the surface of the brain could be detected by feeling the bumps on the surface of an individual's head. 1 He suggested that the bumps, indentations, and overall shape of the skull could be linked to different aspects of a person's personality, character, and abilities.

Most of the confirmed hypotheses found to be fabricated were the phrenological studies conducted by Dr. Franz Joseph Gall discredited in the nineteenth century. Phrenology was a popular pseudomedicine in the late 19th century that posited measurements and other characteristics of the human skull determined different aspects of a person's actions and personality.
By the 1840s, phrenology had lost much of its credibility as a scientific hypothesis. This was only partially caused by mounting evidence that refuted phrenology. [40] Phrenologists struggled to locate the mental organs and were never able to agree on even the most basic mental organ counts, which ranged from 27 to over 40. Organ placement was determined by phrenologists using cranioscopic readings of the skull. According to research performed by Jean Pierre Flourens on pigeon brains, the loss of some brain regions either had no effect on function or resulted in the loss of a function entirely unrelated to that which phrenology had assigned to that region. Although not flawless, Flourens' experiment appeared to show that Gall's purported organs were fictitious.
Since phrenology was used by businesspeople to abuse the middle and working classes, scientists had also lost faith in it. The popularisation of phrenology led to its simplicity and the incorporation of physiognomic principles, which Gall had initially dismissed as a personality predictor. From the beginning, phrenology was tarnished by claims that it promoted materialism and atheism and undermined morals. All of them contributed to the demise of phrenology. Recent research have further debunked phrenology claims utilising cutting-edge technologies like magnetic resonance imaging.

The glycogen phosphorylase enzyme carries out a phosphorolysis reaction resulting in the formation of free glucose. glucose-6-phosphate. glucose-1-phosphate. maltose.
Answers
The glycogen phosphorylase enzyme carries out a phosphorolysis reaction resulting in the formation of glucose-6-phosphate.
The Phosphorolysis reaction:
The glycogen phosphorylase enzyme catalyzes the phosphorolysis of glycogen, breaking down the glycogen molecule into glucose-1-phosphate units. This reaction involves the transfer of a phosphate group from the glycogen molecule to an inorganic phosphate molecule, resulting in the release of glucose-1-phosphate.
This free glucose-1-phosphate molecule can then be converted to glucose-6-phosphate by the enzyme phosphoglucomutase. From there, the glucose-6-phosphate can enter glycolysis or other metabolic pathways to produce energy for the cell. Therefore, the correct answer to your question is glucose-1-phosphate. This process involves the breaking of the glycosidic bond in glycogen using inorganic phosphate, which then produces glucose-1-phosphate as the main product.

1)Describe the one example of a population attribute that would be a good indicator of each of the following:
a)Whether the population is increasing or decreasing:
b) The ability of the environment to support the population:
Answers
Population attributes for given question are a) Birth rate minus death rate b) Carrying capacity
a) Whether the population is increasing or decreasing:
A good population attribute that can be an indicator of whether a population is increasing or decreasing is the "birth rate minus death rate". This attribute provides information on the net change in population, taking into account both new births and deaths. If the result is positive, it indicates that the population is increasing, while a negative result signifies a decreasing population.
b) The ability of the environment to support the population:
A useful population attribute to indicate the ability of the environment to support the population is the "carrying capacity". Carrying capacity refers to the maximum number of individuals that an environment can support without causing long-term damage to the ecosystem. This attribute takes into account factors such as available resources, predation, and disease. If the current population is significantly below the carrying capacity, it suggests that the environment can support the population, while if the population is close to or exceeding the carrying capacity, it may indicate that the environment is struggling to support the population.

What is a isotonic solution? How does it affect a red blood cell?
What is a hypertonic solution? How does it affect a red blood cell?
What is a hypotonic solution? How does it affect a red blood cell?
Answer plz!
Answers
Answer: If you place an animal or a plant cell in a hypertonic solution, the cell shrinks
Explanation: because it loses water ( water moves from a higher concentration inside the cell to a lower concentration outside ). ... A single animal cell ( like a red blood cell) placed in a hypotonic solution will fill up with water and then burst.
An isotonic solution is one wherein the solute concentration across the semipermeable membrane is the same resulting in an equilibrium state.
They do not shrink or swell in an isotonic saline solution, i.e., 0.9% w/v solution of sodium chloride
Hypertonic solution: A solution that contains more dissolved particles (such as salt and other electrolytes) than is found in normal cells and blood.
Now, let’s suppose RBCs are placed in a solution with a sodium chloride concentration of 2% w/v. The sodium chloride concentration of 2% w/v is greater than the RBC’s sodium content and hence the solution is hypertonic. This will result in shrinkage of the RBCs known as crenation
When a solution has a lower solute concentration than the solution present across the semipermeable membrane, it is known as a hypotonic solution. As a result, when a cell is placed in a hypotonic solution, an osmotic pressure gradient forces the solvent to move into the cell in order to attain equal solute
In another situation, let’s suppose RBCs are placed in a solution with a sodium chloride concentration of 0.1 % w/v. The sodium chloride concentration of 0.1% w/v is less than the RBC’s sodium content and hence hypotonic saline. This will result in swelling and eventually bursting of the RBCs which will result in the release of hemoglobin. This is known as hemolysis which is a very dangerous situation.
