Question

Which of these processes liberate energy?

(a) Formation of protein from amino acids

(b) Formation of glycogen from glucose

(c) Formation of lactic acid from glucose

(d) Formation of cholesterol from acetic acid

This question was posed to me during an internship interview.

Asked question is from Biomolecules in division Biomolecules of Biology – Class 11

Answer 1

The correct option is (c) Formation of lactic acid from glucose

To elaborate: The conversions of amino acids to proteins, glucose to glycogen and acetic acid to cholesterol are anabolic processes. The formation of lactic acid from glucose is a catabolic process and liberates energy.
