If acid is not produced in the stomach, what will happen to protein digestion?
Answer and explanation
Correct answer: The protein-digesting enzyme will not work properly
Stomach hydrochloric acid provides the low-pH environment required for pepsin to become active and digest proteins. If acid is absent, pepsin activation and its activity are greatly reduced, so protein digestion in the stomach becomes incomplete or weak. Digestion may continue later through other enzymes in the small intestine, but the stomach stage is impaired. Hence option A is correct; the remaining choices describe unrelated or biologically impossible events.
