Question

Which of these conditions signify an exothermic reaction?

(a) The energy of the product is lesser than that of the enzyme-substrate complex

(b) The energy of the product is higher than that of the substrate

(c) The energy of the product is lesser than that of the substrate

(d) The energy of the product is equal to that of the substrate

I have been asked this question by my college director while I was bunking the class.

I need to ask this question from Biomolecules topic in division Biomolecules of Biology – Class 11

Answer 1

The correct option is (c) The energy of the product is lesser than that of the substrate

Explanation: In an enzymatic reaction, a substrate is converted into a product via the formation of a higher energy enzyme-substrate complex. If the energy of the product is lesser than that of the substrate, it signifies an exothermic reaction.
