Answer:
add a water molecule to break bonds.
Explanation:
Fat digestion occurs in the small intestine where pH is alkaline. Protein digestion starts in the stomach at acidic pH but is completed in small intestine under the conditions of alkaline pH. Both processes use water molecules to break the covalent bonds of the nutrients. Peptidases present in small intestine add water molecules to the peptide bonds that join two amino acids together. This releases the individual amino acids from peptides. Similarly, the enzyme lipase adds water molecules to break the covalent bonds between fatty acids and glycerol of lipid droplets.
