Question

What is true about digestion and absorption of food?

• A. $\text{60\% starch is hydrolysed by salivary amylase}$
• B. $\text{Oxyntic cells secrete pepsinogen}$
• C. $\text{Chylomicrons are small lipoprotein particles passed in intestine into blood capillaries}$
• D. $\text{Glucose and amino acids are absorbed with the help of carrier proteins}$

Answer 1

The correct option is D $\text{Glucose and amino acids are absorbed with the help of carrier proteins}$

Some substances like glucose and amino acids are absorbed with the help of carrier proteins. This mechanism is called the facilitated transport.

30% of starch is hydrolyzed by salivary amylase.
Oxyntic cells secrete HCl and intrinsic factor.
Chylomicrons are very small protein coated fat globules which are transported into the lymph vessels in the villi.
