Which of the following could be absorbed by cells lining the digestive tract? View Available Hint (s) Which of the following could be absorbed by cells lining the digestive tract? starches amino acids proteins DNA

The correct answer is amino acids.

Explanation:

When food is consumed it contains nutrients in the form of polymers like starch, proteins, lipids and nucleic acids (DNA). These polymers can not be absorbed directly by the body because of their complexity and larger structures.

Therefore they must be broken down into smaller forms by digestive enzymes. After digestion, they are broken into smaller and simpler forms like amino acids, glucose, fatty acids, etc. Then these simpler forms are absorbed through the digestive tract in the body.

So as amino acid is the simpler form of proteins so it can be absorbed by cells lining the digestive tract.
