The correct answer is D. The nucleus transcribes and releases messenger RNA signalling for the enzymes to be synthesized.
<span>
The nucleus is the site of transcription, production of messenger RNA (mRNA). Because of that, it contains a lot of proteins that either directly are involved in transcription or are involved in regulation. mRNA is exported from the nucleus, after being post-transcriptional modified.</span>
Answer: B)
B) ADP can act as an allosteric activator by slowing the breakdown of fuel molecules if sufficient energy is in the cell. APT can act as an inhibitor by storing resources in more complex molecules. That is an example of feedback inhibitor because when the end product of the substrate is finished, it can bind to the allosteric site, which will result in the enzymes active site no longer being able to bind with the new substrates. And that is responsible for ATP production because That “stops” the enzyme from making more than necessary and thus wasting chemical resources.
C) Feedback inhibition is a method of metabolic control in which the need of the product of a metabolic that way acts as an inhibitor of an enzyme within that pathway. The APT generating path is an example of feedback inhibition because it controls the amount needed of the product and acts as an inhibitor of the enzyme in the anabolic pathway.
Explanation:
not sure if this is right, I just took stuff out of my bio textbook lol
Explanation:
it shields humans and other living things from ultraviolet rays
Answer:
Xerophyte survival characteristics:
Thick cuticle.
Stomatal closure.
Reduction in # of stomata.
Stomata hidden in crypts or depressions in leaf surface (less exposure to wind and sun).
Reduction in size of transpiration surface (lower leaf only).
Increased water storage.
Explanation:
Xerophyte adaptations increase water intake, limit water loss, and store water efficiently. Water intake adaptations include deep or widespread roots, and high salt content to increase osmosis. Xerophytes have thick cuticles, lost or finely divided leaves, reduced stomata, and CAM photosynthesis
