Answer #1

Catablic pathways are involved in breaking down of complex molecules into simpler ones. For the breakdown, the action of enzymes get necessary. So, the catabolic pathways can be regulated by decreasing or increasing the level of enzymes required for the pathway. If the availability of enzymes will be less, catabolism will be slowed down and vice versa.

Hence, the correct option is (a)

About the incorrect options-

(b) The end products of the pathway are simpler substances, so they cannot acts as regulators.

(c) Not a very sure regulator though.

(d) It depends on the activity of enzymes, as they are the regulators.

Hope it helps, Good luck !!!!

Enzymes (or their production) are often regulated in a negative or positive way, depending on whether they are related to anabolic (building) or catabolic (breaking down) reactions. Please describe, in your own words, why excess of products might inhibit enzymatic activity for anabolic reactions but why excess of reactants might stimulate enzymatic activity for catabolic reactions. This question is pretty complex, so take your time to develop your thoughts prior to typing your answer. The best answers should incorporate aspects...
