No, optimal pH for pepsin is around 2.0 (acidic environment) while optimal pH for rennin is around 6.5-6.7 (slightly acidic to neutral environment). Each enzyme has a specific pH range at which it functions most efficiently due to its unique structure and function.
pepsin
Protease (pepsin) plus hydrochloric acid
the answer is pepsin.
pepsin , rennin , hydrochloric acid
Pancreatic amylase Lipase Pepsin Salivary amylase Maltase Rennin (younger version of pepsin mostly found in babies)
It contains of hydrochloric acid and 2 enzymes, pepsin and rennin. the acidity of hydrochloric acid helps in activating pepsinogen and prorennin(the inactive form of pepsin and rennin respectively)
The function of rennin is to curdle milk proteins by converting the soluble protein caesinogen into the insoluble protein caesinogen. If the new born mammal is unable to produce rennin, then the soluble milk proteins would just pass through the stomach into the duodenum like water. This is bad because the milk proteins would not be able to get digested by the pepsin. However, if there is rennin, the converted insoluble milk proteins would be abe to stay in the stomach long enough for the pepsin to digest it into polypeptides.
pepsin
Becouse colorless watery acidic digestive fluid that is secreted by various glands in the mucous membrane of the stomach and consists chiefly of hydrochloric acid, pepsin, rennin, and mucin. salman

Pepsin is a digestive protease released by the chief cells in the stomach that functions to degrade food proteins into peptides
