My doubt is from Biomolecules in chapter Biomolecules of Biology – Class 11

Answer 1

Correct option is (d) Formation of protein from amino acids

The explanation: The conversions of glucose to pyruvate, glycogen to glucose and cholesterol to acetic acid are catabolic processes. The formation of proteins from amino acids is an anabolic process and requires energy input.
