homework : d
1. describe the digestion of carbohydrate
2. describe the digestion of fat
3. describe the digestion of protein
(mention: organs, enzymes and products)
sample answer of digestion of protein 
(no digestion of protein in mouth and oesophagus),
stomach can release HCl and protease, Hcl provide pH2 for protease to digest small amount protein into amino acid,
in small intestine, Pancreas release pancreatic juice which contain NaHCO3 and protease, NaHCo3 can neutralise HCl and providing optimum pH for proteases released by pancreas and small intestine.
protease can break down protein into amino acid.
