Homework Help: Honors Biology

Posted by Emily on Thursday, September 11, 2008 at 10:29pm.

This graph on my worksheet shows the rate of chemical reactions with the enzymes pepsin and trypsin present in certain pH conditions. It shows pepsin works in a pH level between around 1 to 5, and trypsin works in a pH level between 4 and 9. In earlier questions I stated pepsin would be the enzyme that works in the stomach (pH = 2) and trypsin would work in the small intestine (pH = 8). Sorry this is the best I can explain it! :-(

The question asks: "What must happen to the liquid as it passes from the stomach to the small intestine for digestion to occur normally?"

I have NO idea. Any help is GREATLY appreciated!!! :-)
