Question

Quizplus · Accepted Answer

All of the listed choices are examples of cofactors. Zn+2, Mg+2, and Ni+2 are metal ions that bind to enzymes and facilitate their catalytic activity. Biotin and Thiamine pyrophosphate are organic compounds that bind to enzymes and act as coenzymes. Pyridoxal phosphate and Coenzyme A are also organic molecules that bind to enzymes, facilitating their function. Therefore, the best choice is E, as it includes all the correct examples of cofactors.
