Question

Explain how pepsin optimum ph is suited to its working environment

Answer 1

Pepsin works in the highly acidic conditions of the stomach. It has an optimum pH of about 1.5. On the other hand, trypsin works in the small intestine, parts of which have a pH of around 7.5. Trypsin's optimum pH is about

Answer 2

The reason pepsin functions best at pH 2 is because the carboxylic acid group on the amino acid in the enzyme's active site must be in its protonated state, meaning bound to a hydrogen atom. ... Pepsin is most active at pH 2, with its activity decreasing at higher pH and dropping off completely at pH 6.5 or above
