Source and substrate product of enzymes

Question

what are the sources and substrate products of amylase, protease, and lipase?

Answer 1

amylase:

2 sources: salivary glands (which secretes salivary amylase)

pancreas (which secretes pancreatic amylase)

substrate: starch (it is reduced into maltose by the amylase)

protease:

group of enzymes that hydrolise proteins

sources: stomach (secretes pepsin), pancreas (secretes trypsin, chymotrypsin and carboxypeptidase) , intestinal glands (secrete aminopeptidase)

substrate: proteins and peptides (peptide bonds)

lipase:

source: pancreas

substrate: lipids (the lipids are hydrolized into glycerol and fatty acids by the lipase)
