Which of the following statements about carbohydrate digestion and absorption is true?

Question 2 options:

Human enzymes can break both alpha and beta bonds.


Pancreatic amylase is secreted into the stomach and helps to break down the disaccharide lactose.


Some carbohydrate is still intact when it enters the large intestine.


All of these are correct.

Respuesta :

Answer:

human enzymes can break both

Explanation:

The TRUE statement about carbohydrate digestion and absorption is some carbohydrates are still intact when they enter the large intestine.

  • The beta (β) 1-4 glycosidic bonds of carbohydrates such as cellulose can not be broken down by human digestive enzymes.

  • Pancreatic amylase is a digestive enzyme secreted into the small intestine.

  • This enzyme (pancreatic amylase) is able to cleave amylose to maltose.

  • Carbohydrates that are not digested in the small intestine pass into the large intestine in order to be digested by specialized microorganisms (i.e., colonic bacteria that can ferment nutrients).

In conclusion, the TRUE statement about carbohydrate digestion and absorption is some carbohydrates are still intact when they enter the large intestine.
