Biochemistry C785 Module 2 Quiz 2020 – Western Governors University Which of the following are possible effect(s) that phosphorylation/dephosphorylation can have on the activity of an enzyme? Select one or more: a. Alter the amino acid sequence of the enzyme Incorrect. Phosphorylation is a post-translational modification, meaning that it occurs after the protein is made and the amino acid sequence has been completed. Phosphorylation can alter the conformation of an enzyme, but not the a...
