Answer 1

Step-by-step explanation:

In the small intestine, enzymes are secreted on the food substances for digestion to take place before absorption in the villi in the small intestine occurs.

For carbohydrates,they are initially called maltose hence the enzyme maltase is secreted on the maltose to convert it into glucose molecules which is needed for the body.

For proteins,they are initially called peptides and polypeptides.An enzyme erepsin is secreted on the peptides and the polypeptides by the small intestine to convert them to amino acids which is also needed by the body.

For fats and oils,they are digested in the duodenum by an enzyme called lipase which coverts them to fatty acids and glycerol before it gets into the small intestine to be absorbed.
