Largest variety of hydrolases are present in omnivores, while the herbivores, generally lack digestive enzymes II. Digestive enzymes are of four types namely, amylase, proteinases, lipases and nucleases III. Proteinases are also known as proteases which are released in the active form because the proteins, either cellular or extracellular, all are hydrolysed by them in the absence of food IV. Hydrolases and cholecystokinin are secreted by the exocrine part of pancreas

Assertion: Vitamins are essential for healthy life.

Reason: Vitamins regulate metabolism.
