C6H12O2+6O2=6CO2+6H20+ATP'S
Aerobic respiration takes place in the presence of oxygen
Aerobic respiration has 4 stages
Anaerobic respiration has 2 stages
Aerobic respiration has 4 stages
- Glycolysis (sugar splitting) happens in the cytoplasm Splits 6 carbon sugar into 2-3 carbon sugars pyruvate. There are two steps to glycolysis energy input and energy output. It produces 2ATPs and 2NADHs
- Pyruvate oxidation connects glycolysis to the Krebs cycle and modifies pyruvates so they can be used the Krebs cycle and remove a CO2 and the CO2 exits the cell
- The Krebs cycle Transfers energy from organic molecules to ATP, NADH and FADH2. The Krebs cycle happens 2 time per glucose molecule. The modified pyruvate enters the cycle and the -COA leaves and goes to modify another pryuvate. In one Krebs cycle 3NAD+, FAD+ from NADH and FADH2. Two CO2 are produced
- Electron transport chain happens in the inner mitochondrial membrane. Oxygen is the final proton acceptor. Hydrogen ion gradient drives ATP synthesis. Hydrogen ions are pupped across the mitochondrial membrane. Then the ATP moves thought the membrane into the cytoplasm.

- Alcohol fermentation happens in yeast in witch NADH passes is hydrogen ions to generate CO2, ethanol and NAD+. CO2 is removed from a pyruvate to form ethanol
