Cellular Respiration

• C6H120602 ? 6CO2 6H2O Energy
• Oxidation of glucose is a step by step process
• 40 of energy is used to make ATP
• In automobiles only 25 of energy captured

5
Glycolysis

• Glyco sugar
• Lyse- to break
• First set of reaction to break down sugar
• Occurs in the cytoplasm
• anaerobic

6
3 steps not pictured
Must add 2ATP to start the reaction
2ATP from each PGAL are made as well as 1NADH
PGAL
3 steps not pictured
Net gain 2ATP and 2NADH

Anaerobic respiration

• Breakdown of glucose w/o oxygen
• Obligate anaerobes (oxygen is poisonous to them)
• Facultative anaerobes
• Can do aerobic or anaerobic respiration

11
Anaerobic respiration fermentation

• 2 Pathways
• Alcoholic fermentation
• Lactic acid fermentation
