why can't a linear protein (in its primary structure) reach the whole way through the lipid bilayer?

Answers

Answer 1

A linear protein, also known as a polypeptide chain, cannot span across the entire lipid bilayer because the hydrophobic core of the membrane is unfavorable to water-soluble amino acids. The hydrophobic core of the bilayer, formed by the tails of the phospholipid molecules.

Creates a nonpolar environment that repels polar amino acids. As a result, linear proteins are unlikely to pass through the membrane completely.

Amino acids that are nonpolar or hydrophobic, on the other hand, are favored by the hydrophobic core of the bilayer. The hydrophobicity of these amino acids.

On transcribing DNA, a strand of RNA which is complementary to the DNA is generated. The major difference between the DNA and RNA strands is the replacement of T (thymine) with U (uracil) in the RNA strand.

This RNA leads to formation of amino acids and in turn, the formation of proteins by undergoing translation. The nucleotides are read in a group of three known as a codon. This codon codes for a specific amino acid.

AUG codes for Methionine (Met), UCC codes for Serine (Ser), CCU codes for Proline (Pro), ACA codes for Threonine (Thr), AAG codes for Lysine (Lys), UGA codes for Stop Codon (Ter) and so on.

Anatomical features that show an underlying structural similarity even though their superficial structure is different are termed: dependent structures homologous structures symplasic structures homoplasic structures

Answers

Anatomical features that show an underlying structural similarity even though their superficial structure is different are termed homologous structures.

Homologous structures are anatomical features that have a common origin and underlying structural similarity, despite their external or superficial differences. These structures are derived from a shared ancestor and may have different functions or appearances due to adaptations to different environments or specialized roles.

Homologous structures often share a similar underlying anatomical organization, such as bone structure or basic arrangement of tissues. They may serve different functions in different organisms, but their fundamental structure and developmental origin remain similar. Examples of homologous structures can be seen in the forelimbs of vertebrates, such as the arms of humans, the wings of birds, and the flippers of whales.

Answers

A segment of the Vibrio fischeri genome containing genes responsible for bioluminescence was cloned and transferred into Escherichia coli to screen for the specific genes involved in the production of bioluminescence. The resulting recombinant E. coli strain emitted light, indicating successful transfer of the bioluminescence genes.

To identify the genes responsible for bioluminescence production in Vibrio fischeri, scientists use a technique called genetic cloning. They isolate a segment of the Vibrio fischeri genome containing the bioluminescence genes and insert it into the genome of Escherichia coli. If the transfer is successful, the recombinant E. coli strain will produce light, indicating that the bioluminescence genes have been successfully transferred. By analyzing the recombinant strain, scientists can determine which genes are responsible for the bioluminescence production and gain insights into the genetic mechanisms underlying this fascinating biological phenomenon.

Answers

If we add more carbonic acid then the equilibrium position would shift to the right

What is the direction of the equilibrium shift?

A chemical reaction at equilibrium shifts to the right to offset the change when additional reactants are added. Le Chatelier's principle, which holds that an equilibrium system will respond to a change by moving in a direction that minimizes the influence of that change, governs this movement.

carbon dioxide can build up waste and disrupt a cells homeostasis which statement best describes how a cell gets rid of excess carbon dioxied

Answers

Answer:

The primary mechanism by which a cell gets rid of excess carbon dioxide (CO2) is through a process called respiration or cellular respiration. In cellular respiration, cells break down glucose and other organic molecules in the presence of oxygen to produce energy in the form of ATP (adenosine triphosphate), along with carbon dioxide and water as byproducts.

Once carbon dioxide is generated during cellular respiration, it diffuses out of the cell and into the surrounding tissues and fluids. From there, it enters the bloodstream and is transported to the lungs. In the lungs, carbon dioxide is exchanged for oxygen through the process of gas exchange during breathing. Oxygen is taken up by the red blood cells, while carbon dioxide is released into the air as we exhale.

In summary, cells eliminate excess carbon dioxide by releasing it into the bloodstream, where it eventually reaches the lungs for exhalation.

2. Based on your answer to question 1, what do you think could be done to reduce levels of
carbon dioxide in the atmosphere? What could people change that would reduce the burning
of fossil fuels? (10 points)

Answers

Answer: Carbon dioxide (CO2) is a colorless gas that is naturally present in the air as a result of the natural carbon cycle of our planet. While emissions come from many natural sources, it is the CO2 produced by manmade processes such as fossil fuel combustion and power plant emissions that are problematic. This, in combination with the destruction of natural carbon dioxide sinks through deforestation, is creating an unhealthy environment on our planet and contributing significantly to climate change. here are other things still that can be done to help improve our carbon dioxide situation, even if they aren't tasks the average person can control. For example, as a society, we must continue to push for improved technology in our power plants, so our energy consumption does not produce as much waste.  Improving technology will also help more directly with how much electricity we use. Appliances and electronics are more efficient now than they have ever been in the past, but we should always strive for better regardless. Doing your individual part may not seem like much in the grand scheme of things, but if everyone does their best, it will eventually add up to a significant improvement in the fight against climate change.

what is the source of atp for cardiac muscle contraction

Answers

The source of ATP for cardiac muscle contraction is primarily generated through oxidative phosphorylation, which occurs in the mitochondria of cardiac muscle cells. The electron transport chain in the mitochondria produces a gradient of hydrogen ions that are used by ATP synthase to produce ATP. This process is known as oxidative phosphorylation because it uses oxygen as the final electron acceptor to produce water.

The cardiac muscle has a high energy demand, as it must continually contract and relax to maintain blood flow. Therefore, it is reliant on a steady supply of ATP to meet its energy needs. In addition to oxidative phosphorylation, ATP can also be produced through glycolysis, which occurs in the cytoplasm of cardiac muscle cells. However, this process is much less efficient than oxidative phosphorylation and can only provide a limited amount of ATP.

The source of ATP for cardiac muscle contraction is crucial for the proper functioning of the heart. Any disruptions in ATP production can lead to a decrease in cardiac output, which can result in a range of cardiovascular disorders.

DNA polymerization is the process of synthesizing a new DNA strand from a pre-existing template. This process, as well as other processes such as DNA replication and protein synthesis, are examples of biological polymerization.Let's learn about the strand names in the DNA molecule.There are two strands in DNA, one of which is called the leading strand, and the other is called the lagging strand.

When DNA is replicated, one strand of the parent molecule serves as the template for the complementary strand that is synthesized. The parent strand that runs in the direction from 3’ to 5’ is referred to as the template strand, while the newly synthesized complementary strand that runs in the opposite direction from 5’ to 3’ is referred to as the leading strand.Therefore, DNA polymerization takes place continuously on the leading strand.
