A) covalent modulator
B) competitive inhibitor
C) allosteric modulator
D) reversible antagonist
E) irreversible agonist

Question

Quizplus · Accepted Answer

The phosphorylation of glucose involves the transfer of a phosphate group from ATP to glucose by a specific enzyme called hexokinase or glucokinase. This results in the formation of glucose-6-phosphate, which is a less permeable molecule and helps maintain a low intracellular concentration of glucose. The transfer of a phosphate group involves the formation of a covalent bond between the phosphate and the glucose molecule. Therefore, the enzyme that phosphorylates glucose acts as a covalent modulator, which means that it modifies its substrate by forming a covalent bond.
