Which of the following enzymes carries out the initial step in the digestion of milk in humans?

Options

  1. ARennin
  2. BLipase
  3. CTrypsin
  4. DPepsin

Correct answer

D. Pepsin

Step-by-step solution

In human milk protein digesting enzyme in stomach is pepsin. In calves it is renin. It is also present in small amounts in human infants but not adults. Pepsin acts on water soluble 'caseinogen (milk protein) to form soluble 'casein'. This combines with calcium salts to form insoluble calcium paracaseinate, which gets readily digested enzymatically.
