What is the question your just stating something with steps.
The answer is it's combination of alleles for a specific one.
B, the enzyme loses its shape and is no longer able to catalyze reactions.
All are part of domain Archaea. Archaeabacteria are prokaryotic or no nucleus present and are <span>unicellular organisms. They are often characterized as having the ability to thrive in extreme conditions. Mesophiles are found in high salt content areas. Thermophiles in high temperature areas. Acidophiles in high pH areas.</span>
Answer:
b) Glutamate's negatively charged R group mimics a phosphorylated serine residue. The Vmax is reduced because the carboxyl group is smaller and less charged than a phosphate group.
Explanation:
Vmax is the maximum velocity of a reaction. It is achieved when all the binding sites of an enzyme are occupied. Glycogen phosphorylase enzyme has a serine residue on position 14. Serine is important for its activity because serine's phosphorylation activates it. Hence, phosphorylated Glycogen phosphorylase is active.
Serine has a hydroxyl group which acts as a nucleophile leading to its phosphorylation and addition of negative charge. Glutamate is already a negatively charged amino acid so it repels the phosphoryl group. However because of its negative charge it acts like phosphorylated serine, making the enzyme functionally active. But due to lesser negative charge and smaller size as compared to phosphoryl group, it is not able to fully restore the wild type Vmax.
