Q1- Curdling of milk in stomach occurs by the action of which enzyme ?
(a)- Chymotrypsin (b)- Lipase
(c)- Chymosin (d)- Amylase
Ans- (c)- Chymosin also known as Rennin is responsible for curdling of milk in gut of Infants and other milk-feeding young animals.
Q2- (A)- Surgical Removal of the Gall Bladder is called Cholecystectomy.
(B)- Crypts Of Lieberkuhn are found in Large Intestine.
(a)- A is true, B is False. (b)- A is false, B is True.
(c)- Both are True. (d)- Both are False.
Ans- (a)- A is true, B is False. because Crypts Of Lieberkuhn are found in Small Intestine, not in Large Intestine.
Q3- What is Glomerular Filtrate ?
Ans- The filtered Blood from Glomerulus entering into Bowman's Capsule is called Glomerular Filtrate.
Glomerular Filtrate = Blood - (Blood Corpuscles + Plasma Proteins).
