Not all enzymes have substrate specificity. For example, pepsin can breakdown numerous types of proteins in the stomach. What concept best describes why the single enzyme pepsin can breakdown so many proteins?
A) the law of mass action
B) the induced -fit model
C) complementary base pairing rule
D) ligand -protein interactions
E) the lock -and -key model

Question

The induced-fit model explains how enzymes can adapt their shape to fit different substrates, allowing enzymes like pepsin to act on a variety of proteins by changing shape to accommodate the substrate.
