If the chemical enzyme pepsin was mixed with some proteins in a test tube in a laboratory, which of these outcomes would you predict? A) Pepsin would probably NOT break down proteins in the test tube because enzymes cannot exist outside of the human body. B) Pepsin would partially break down the protein molecules but would not work well due to the absence of DNA in the test tube. C) Pepsin would probably NOT break down proteins in the test tube because pepsin is designed to work at very acidic pH ranges. D) Pepsin would break down the protein molecules equally well in the laboratory as in the human stomach since it is a stable chemical.

Answer;

C) Pepsin would probably NOT break down proteins in the test tube because pepsin is designed to work at very acidic pH ranges

Explanation;

Enzyme pepsin is a proteolytic enzyme produced by the chief cells of the stomach walls, its function is to break down protein molecules into smaller molecules called peptides. The enzyme works best at low pH (acidic pH) in the stomach, enhanced by the production of hydrochloric acid in the stomach.

Tommy Hernandez · Answer 2

based on the occurence, the outcome what i would predict would be : c. pepsin would probably not break down proteins in the test tube because pepsin is designed to work at very acidici pH ranges under non-acid Condition, pepsin is internalized by cells of the upper airways
