All of the following are co-enzymes except:
Correct answer: D. ADP
- A. NAD
- B. FAD
- C. NADP
- D. ADP
Explanation
Coenzymes are non-protein, organic compounds required by many enzymes for catalytic activity. They are often vitamins or derivatives of vitamins. The main function of coenzymes is to act as intermediate carriers of transferred electrons or functional groups in a reaction.ADP (adenosine diphosphate) is a biological molecule consisting of one adenine, one sugar, and two phosphates. Its most important role is that it is combined with a phosphate molecule to make ATP, the premier energy molecule in living cells. ADP is also used to help activate platelets in clotting. ADP is not a coenzyme.

About Characteristics of Enzymes
Enzymes are globular biological catalysts that lower activation energy without being consumed, usually showing specificity for particular substrates. Questions cover active sites, enzyme substrate complexes, the lock and key and induced fit models, intracellular and extracellular action, and the effects of denaturation, while distinguishing enzymes from non biological catalysts.
