An enzyme in gastric juice of many infant mammals that precipitates milk protein is:
Correct answer: C. Rennin
- A. Renin
- B. Personage
- C. Rennin
- D. Gastrin
Explanation
Rennin, also known as chymosin, is the correct answer. It is an enzyme found in the gastric juice of many infant mammals, including humans, that helps in the digestion of milk protein by coagulating it. The other options are incorrect because 'Renin' is a misspelling of the correct enzyme 'Rennin', 'Personage' is not a relevant enzyme, and 'Gastrin' is a hormone, not an enzyme involved in milk protein digestion.
