Answer:
D. Allosteric activator
Explanation:
In an enzyme, the allosteric site is a site/motif different from the active site, (i.e., the site with catalytic activity) which is able to interact with regulatory effector molecules in order to activate or inhibit enzymatic activity by influencing the tridimensional (3D) structure of the enzyme. An allosteric activator is an effector molecule with the ability to bind to a specific enzyme at a different site than the active site, thereby modifying the shape of the enzyme and increasing the affinity of this enzyme for its substrate. Moreover, Adenosine monophosphate (AMP) is a nucleotide composed of a phosphate group, a sugar ribose, and an Adenine (A) base. This effector molecule (AMP) has shown to allosterically stimulate diverse enzymes in physiological conditions (e.g., AMP-activated protein kinase).
Is the question multiple choice?
Answer:
Water is not required for the fertilization.
Explanation:
The plants can reproduce by the means of asexual reproduction and sexual reproduction. The pollen grains and egg cell fertilize with each other in the sexual reproduction.
The seedless vascular plants and non vascular plants required the means of dispersal for their fertilization. Their egg cell fuses with the pollen grains that are dispersed by animals or wind. Water is not required for the fertilization of the vascular plants.
Longitude? maybe,,Not sure
Quality and features of the soil is very important as many plants and organisms breed and feed in soils
