Anaerobic respiration

Fermentation

oxygen cannot be delivered to the mitochondria in the muscles fast enough, NADH cannot be oxidized in ETC, therefore the aerobic pathway will halt once NAD+ runs out

Lactate Fermentation

* Pyruvate reacts with NADH to reoxidize it into NAD+
* pyruvate is turned into lactate (lactic acid)
* Lactate is utilized by resting muscle cells
* when oxygen is available, lactate is converted into pyruvate or glycogen

Ethanol Fermentation

* Pyruvate is converted into ethanol and CO2
* used in baking and alcohol

ATP

less efficient at producing ATP, only produces the amount used in glycolysis
