Answer Key / Explanation : (d) -

(d)

In humans, milk protein digesting enzyme in stomach is pepsin. In calves it is rennin. It is also present in small amount 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.
