Unformatted text preview: ugar molecule (ribose) and three phosphate groups ATP is broken down to Adenosine diphosphate in a hydrolysis reaction which produces energy to power many eventsin the body: ATP + H2O ­­­> ADP + Pi + Energy 4.9 ATP: The Energy Currency nergy Requiring Processes ATP Hydrolysis ATP + H20 ADP + Pi ATP serves as the universal energy donor. The energy derived from the breakdown of fuels (exergonic reaction) drives the formation of ATP (endergonic reaction). The ATP in turn is hydrolyzed and the resultant energy is used by the cell for a variety of processes such as: 1) Na+/K+ Pump, 2) Muscle Contraction, 3) Ca2+ Pump .10 Introduction to Chemical Reactions III Irreversible Reactions can only proceed in one direction: A + B C+ D Reversible Reactions can proceed in either direction A + B C + D 4.11 Oxidation/Reduction Reactions Oxidation­reduction reactions are those in which electrons (e) are transferred from one molecule to another. Reduced A Oxidation: A:e Oxidized A A + e Oxidized B Reduction: B + e Reduced B B:e Combined: A:e + B A + B:e...
