Activity of an enzyme can be modulated by change of A) pH B) Light C) Humidity D) Rainfall
Option A) Changes in pH which can accompany metabolic process such as respiration (aerobic glycolysis for example) can alter the conformation of an enzyme and hence enzyme activity. The initial changes are covalent (change in protonation state of the protein) which can lead to an alteration in the delicate balance of forces that affect protein structure
