Digestion And Absorbtion

Question 1

What happens during digestion

Answer 1

Large molecules are hydrolysed into smaller molecules that can be absorbed across the cell membrane

Question 2

Outline how carbohydrates are digested

Answer 2

SAM:
Starch is hydrolysed by the salivary amylase (which is secreted by the salivary glands into the mouth) into maltose

PAM:
The pancreas releases pancreatic enzymes into the small intestine. This contains amylase which hydrolyses any remaining starch into maltose
MEG:
The enzyme maltase which is embedded In the epithelial cells in the small intestine hydrolyses the maltose into glucose, which can then be absorbed into the bloodstream through the epithelial lining
