Answer #1

a) -protein digestion start in stomach .Pepsin is the protein digestive enzyme in stomach. pepsin breaks the peptide bond which hold the molecule together. protein digestion is complete in small intestine by pancreatic enzymes trypsin, chymotrypsin and carboxypeptidase.

b) -some digestion of fat occur in mouth and stomach but most takes place in small intestine .Bile from liver emulsify fat globules into smaller droplets.lipase is the enzyme which digest the lipid.

The mass ratio of proteins vs lipids varies depending on the function and location of the membrane. Where might you find a membrane containing about 75% protein and 25% lipids? (hint: one place at least is an organelle) How about ~50% protein and 50% lipids? How about a membraneLess than 25% protein? (Hint: in somewhere in the brain)
