Show Answer
Answer:
Correct Answer: C
Solution:
- Rennin or chymosin is a protease found in rennat. It causes cleavage of a specific linkage, i.e., the peptide bond between 105 and 106 phenyl alanine and methionine and K-casein, the native substrate of this enzyme. Thus, its pressure helps in the conversion of milk into curd via changing the caesin protein of milk into caesinate.
