Which of the following statements is correct regarding isozymes?
A) they catalyze the same reaction but have vastly different structures
B) they are always monomeric proteins
C) their differences are based upon the type of tissue in which they are present
D) they often respond to different inhibitors and activators
E) both c and d are correct

Question

Quizplus · Accepted Answer

Isozymes are enzymes that catalyze the same reaction but have different structural and functional properties due to their expression in different tissues or under different conditions. Therefore, option C is correct. Additionally, isozymes can have different responses to inhibitors and activators, making option D also correct. Therefore, the correct answer is E, both C and D are correct. Option A is incorrect because isozymes can have similar structures with some variations, but they do not have vastly different structures. Option B is also incorrect because isozymes can be monomeric or multimeric proteins.
