Buffers

Naturally occurring molecules that help maintain the
_________________ in cells

A great example of buffers can be found in our blood
Blood Buffering Steps
1. The pH of blood is normally ________ for homeostasis
2. Death can occur if your blood pH is even slightly
__________ or _______________ this pH
3. As your cells produce _________________________, your

a ________________ comes along and grabs the extra
_______________ thus ______________the blood back to a

5. This buffer's name is ___________________ (just like sodium
bicarbonate = ______________________________)
***You will make a cartoon out of these buffer steps. It
can be a comic strip or cartoon.

___________
_____________
____________
