Scientists are researching the effects of a drug used to treat acid reflux on digestion of food in the stomach. Pepsin is an enzyme found in the stomach that is active in digesting proteins.

If the drug being researched dramatically decreases the acidity in the stomach, which of the following is expected to occur?
Pepsin will be less active, causing a decrease in the digestion of proteins in the stomach.
Production of pepsin will increase, resulting in more proteins being digested in the stomach.
The higher pH will stimulate pepsin activity and decreased the amount
The lower pH will cause the denaturing of pepsin and result in digestion of fewer proteins in the stomach.
