Question

Name the correct substrates for the following enzymes:

(a) Trypsin

(b) Amylase

(c) Pepsin

(d) Lipase

Answer 1

Enzyme's substrates:

Trypsin:

1. It is a protein-digesting enzyme.
2. In the duodenum, trypsin breaks proteins down into smaller peptides.
3. It's a proteolytic enzyme, which means it breaks down proteins.
4. Other pancreatic zymogens are also activated by trypsin.

Amylase:

1. It is a starch digesting enzyme.
2. Amylase, a salivary enzyme, aids in the breakdown of big starch molecules into smaller sugar molecules.
3. It's a digestive enzyme that aids in the digestion of starchy meals like potatoes.

Pepsin:

1. Pepsin is the most important enzyme in protein digestion.
2. Proteins are broken down into smaller peptides and amino acids that can be absorbed more easily in the small intestine.

Lipase:

1. Fat is broken down in the mouth by lingual lipase, which is found in saliva.
2. Most of the fat present in the diet is digested in the duodenum by the action of pancreatic lipase.
