Concept:Each enzyme acts only on a specific food substance, so an incorrect link means the enzyme does not digest that particular substrate.
Explanation:Trypsin digests protein in the small intestine, so protein–trypsin is a correct match.
Lipase breaks down fats into fatty acids and glycerol, so fat–lipase is correct.
Pepsin is a protein-digesting enzyme found in the stomach; it does not act on sucrose.
Sucrose is actually digested by sucrase, not pepsin.
Amylase digests starch into maltose, so starch–amylase is correct.
Therefore, the only wrong pair is sucrose–pepsin.
Answer:C.
Sucrose –
Pepsin
