complex carbs made up of simple carbs (sugars)

double sugars

single sugars (3-7 in a chain or ring)

simple carbs

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

maintaining homeostasis both inside and outside cell (electrolyte levels)

important to body functions and abundant in body fluids. helps in homeostasis

anything not containing carbon or hydrogen

compounds with carbon and hydrogen

CO2 + H20 >< H2CO3 ><H+ + HCO3-

chemicals that resist pH change. they donate or take hydrogen ions

(0-6) when H+ concentration increases and solution becomes more acidic. pH also goes down.

(8 or more) when OH- concentration increases and solution becomes more basic. pH goes up

shorthand for the hydrogen ion concentration used to indicate acidic or alkaline condition(0-14)

water and electrolyts from bases. reacting to acids and becoming neutralized

substances that combine with hydrogen ions

electrolytes that release hydrogen ions in water

substances that release ions in water
