Cellular respirationC6H1206 + 6O2 6CO2 + 6H20+ ATP

OIL RIG• OIL=oxidation involves losing e-• RIG=reduction involves gaining e-

NAD+ ---NADH

• NADH--electron holder. Can hold 2 e-. Electrons lose very little energy when they are transferred from glucose to NAD+

FAD—FADH2

• FADH2 holds electrons• FADH2 carries lower energy electrons

than NAD+

ATP--ADP

• PHOSPHORYLATION...    adding a phosphate to ADP                 ADP   +   P    ------>    ATP

• ATP holds more energy than ADP

NO OXYGEN=Fermentation

• In fermentation to pyruvic acid molecules are turned into some “waste” product, and a little bit of energy (only two ATP molecules per molecule of glucose – actually four are produced in glycolysis, but two are used up) is produced.

• Out of many possible types of fermentation processes, two of the most common types are lactic acid fermentation and alcohol fermentation.
