Cellular respiration
C6H1206 + 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
Substrate level phosphorylation

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.
