Question
Chapter 18, Problem 31RE
Interpretation Introduction
Interpretation:
The advantages of controlled mechanisms, such as allosteric factor and covalent modification in the
Concept introduction:
The allosteric effector binds with an active site of a protein in such a way that the conformation and binding properties of another active site of the same enzyme change. This change affects the affinity of the enzyme to its substrate.
In a covalent modification, alternation is done on the proteins present at the active site of the enzymes in order to change the affinity of the enzyme with the target molecule, subsequently affecting the
