Current Question (ID: 14272)

Question:

Which one of the following statement is false regarding digestion and absorption of food in humans?

Options:

1. Oxyntic cells in our stomach secrete the proenzyme pepsinogen.
2. Glucose and amino acids are absorbed with the help of carrier ions like Na⁺.
3. Chylomicrons are small lipoprotein particles that are transported from intestine into blood capillaries.
4. About 30% of starch is hydrolysed by salivary amylase in our mouth.

Solution:

Pepsinogen is secreted into gastric juice from both mucous cells and chief cells. Oxyntic cells secrete hydrochloric acid (HCl) and intrinsic factor. Massive ions like Na⁺ facilitate the absorption of substances like amino acids and glucose through co-transport. Chylomicrons are lipoprotein particles synthesized by intestinal epithelial cells and are transported from intestine into blood capillaries via lacteal. About 30% of starch digestion happens in the mouth. However, it will vary a bit depending on how long food is chewed, how much moisture there is in the mouth, and how much moisture the starch can absorb.
