Solution
The correct option is D Rennin Rennin is a proteolytic enzyme found in gastric juice of infants which helps in digestion of milk proteins. Casein is the protein present in milk which is acted upon by the enzyme rennin and paracasein is formed. Paracasein is further digested by pepsin of gastric juice. Lipase enzyme digests fats. Trypsin is produced from the pancreas and it helps in the digestion of proteins.
