Question

Conversion of substrate to amino acids is called __________

(a) Nitrification

(b) Proteolysis

(c) Peptidase

(d) Deaminase

This question was addressed to me in quiz.

My question comes from Fed Batch Culture topic in portion Microbial Growth Kinetics of Bioprocess Engineering

Answer 1

Correct choice is (b) Proteolysis

Best explanation: Proteolysis is the breakdown of proteins into smaller polypeptides or amino acids. Uncatalysed, the hydrolysis of peptide bonds is extremely slow, taking hundreds of years. Proteolysis is typically catalysed by cellular enzymes called proteases, but may also occur by intra-molecular digestion. Low pH or high temperatures can also cause proteolysis non-enzymatically.
