The enzyme pepsin becomes active when pH isMultiple Choicehigh.low.

Pepsin is an enzyme that digests proteins at acidic pH. Therefore, it must act in theMultiple Choicestomach.small intestine.mouth.large intestine.esophagus.

Pepsin has the optimum pH of

Pepsin is a digestive enzyme that is found in the stomach, where the pH level is less than 3. Trypsin is a digestive enzyme that is found in the small intestine, where the pH level is slightly above neutral. The graph in this figure shows the activity of these enzymes. What would happen if pepsin was placed in the small intestine, and trypsin was placed in the stomach?Multiple ChoiceBoth enzymes would function normally.Pepsin would not function but trypsin would function.Pepsin would function but trypsin would not function.Both enzymes would stop functioning.

7.What happens to the enzyme's active site above the optimum pH?

design an experiment to investigate the effects of albumen concentration on the enzyme pepsin reaction.
