Digestive Enzymes

[Mir]

Should I memorize all the digestive enzymes and their respective sites and functions for the MCAT? Or will I be wasting my time...

wasting your time, just know pepsinogen and pepsin. Also know the 4 main cells of the digestive stomach, ie g cell, cheif cell, parietal cell, and mucous cell and their main functions.

I believe this is what EK says as well

it is, and kaplans doesnt state it, but covers the same material as does Princeton.

It doesnt hurt to know it, but I think you should be able to explain which chemical digestion is taking place in each, for example mouth ( carbohydrate digestion with salivary amylase)

Stomach----protein digestion with pepsin ( functions at a ph of 2 or acidic Ph)

Small intestine ( alkaline ph, starch digestion with pancreatic amylase, protein digestion with carboxypeptidase, trypsin, chymotrypsin e.t.c) . Fat digestion with lipase and so on and so forth.

___ Also being able to know that digestion occurs in the duodeneum and absorption in the jejunum and ileum wall

Yes I think pancreatic digestive enzymes (trypsin, chymotrypsin, pancreatic amylase, lipase) are also important in addition to knowing salivary amylase, pepsin.

huge waste of time. They arent going to be asking specific questions like that. If anything know the bigger picture, where certain macronutrients are broken down and stuff like that.
