carbohydrates
provide energy, supply materials to build cell structures, and store as reserve energy supplies

-
buffers
chemicals that resist pH change. they donate or take hydrogen ions
-
acidosis
(0-6) when H+ concentration increases and solution becomes more acidic. pH also goes down.
-
alkalosis
(8 or more) when OH- concentration increases and solution becomes more basic. pH goes up
-
pH scale
shorthand for the hydrogen ion concentration used to indicate acidic or alkaline condition(0-14)
-
salts
water and electrolyts from bases. reacting to acids and becoming neutralized
-
bases
substances that combine with hydrogen ions
-
acids
electrolytes that release hydrogen ions in water
-
