Care to elaborate?? I know these enzymes r going to b a hot topic on the exam. Could anyone help update what i have so far, or change my mistakes? Thanks!

Mouth- Mechanical digestion; Salivary amylase breaks down polysacc into mono & disacc

Stomach- Chemical & little Mechanical digestion; Pepsin breaks down proteins into AA; Starch is also broken down.

Small Intestine- contains Trypsin, Chymotrypsin, & Carboxypeptide which all break down proteins into AA's; also contains brush border enzymes which also aid in the breakdown of peptides 2 AA & polysacc 2 sugars; contains lipase, amylase & nuclease???

Liver- produces bile & urea; bile salts form micelles 4 digestion & absorption of lipids takes place here; detox

Gallbladder- stores the bile (stim. by the rel. of CCK from the SI)

Pancreas- prod. amylase 2 hydrolize polysacc 2 mono & disacc, prod. lipase 2 breakdown lipid 2 Fatty Acids & Glycerol, prod. esterases 2 hydrolyze cholesterol

Large Intestine- responsible for H20 & Sodium reabsorption

*Most of the Digestion occurs in the Small Intestine

you have quite a few mistakes/typos :)

P.S. You also may want to look at Vit. K and CCK << very important for DAT and NBDE

Pancreas produces Trypsin, Chymotrypsin, & Carboxypeptide which all break down proteins into AA's; Pancreatic amylase which breaks down carbo,and lipase break down fat and are then secreted to the small intestine. Bile is an emulsifier not an enzyme it just breaks down larger fat particles into smaller ones. Hope this helps.
