• A molecule that consists of adenine, sugar, and 3 phosphate groups.
• can be hydrolyzed to release energy
• used by cells to store and transfer energy
• high potential energy

• consists of adenine, sugar, and 2 phosphate groups
• the energy released during the oxidation is used to transfer P to ADP to make ATP

• A class of chemical reactions that involves the loss and gain of electrons
• LEO GER

3 steps of cellular respiration

1. glucose is broken down to pyruvate
2. pyruvate is oxidized to CO2
3. compounds reduced in steps 1 and 2 are oxidized in processes that usually lead to production of ATP

• Series of chemical reactions, during which acetyl CoA (from glycolysis) is broken down to CO2, producing ATP and reduced compounds for the ETC. 
• Occurs in the mitochondria
• When completed, Glucose is completely oxidized to CO2
• PYRUVATE enters and CO2, NADH, FADH2, and ATP come out

• a set of molecules involved in a coordinated series of redox reactions in which the potential energy lost by electrons is used to pump protons from one side of the membrane to the other.
