Go through the following statement regarding the physiology of digestion and identify wheather they are true or false Choose an appropriate option from the codes given below I. 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 |

Protein hydrolysing enzymes are called peptidases or proteases. A majority of protein hydrolases are secreted in inactive forms called proenzymes as their active forms can digest cellular or extracellular proteins of individuals itself. Hydrolases secretin and cholecystokinin are secreted by the duodenum of intestine and epithelium of the entire small intestine, respectively
