ACID - BASE CHEMISTRY

Many important inside cells are acids or bases. An acid is a substance that can donate a proton (H+) or accept an electron pair.

A base is a substance that can accept a proton (H+), release OH-, or donate an electron pair. A base is also called an alkali

Most of the water in living organisms is in the form of molecules. A small number of water molecules in living organism dissociate, or break apart, into hydrogen ions (H+) organisms dissociate, or break apart, into hydrogen ions (H+) and hydroxide (OH-) ions.
