Question 3
Describe the process of protein absorption in the small intestine
Observation
This question was attempted by many candidates and their performance was poor. Candidates could not correctly describe the process of protein absorption in the small intestine.
The expected answers are as follows:
3. DESCRIPTION OF THE PROCESS OF PROTEIN ABSORPTION IN THE SMALL
INTESTINE
- the presence of villi enhances/increases the process of absorption of amino acids/ protein
- the walls of the villi contains blood capillaries
- into which the digested proteins diffuse
- and later into the hepatic portal vein
- and finally into the liver and the small intestine
- from where it leads into the heart for circulation into the body
