Question

Which one of the following is the matching pair of digestive enzyme and substrate?

• A. Rennin - Protein
• B. Amylase - Lactose
• C. Trypsin - Starch
• D. Invertase - Maltose

Answer 1

The correct option is A Rennin - Protein

In young mammals, milk protein caseinogens are digested with the help of an enzyme, called rennin. It converts prorennin into active rennin in the presence of HCl. Rennin curdles milk protein caseinogens, which is hydrolyzed into casein. Rennin converts casein into solid calcium paracaseinate in presence of Ca${}^{++}$ so that pepsin can reduce it to peptones.
