Two types of anaerobic respiration, but lactate fermentation is the only one needed for exam.
Lacatate fermentation occurs in animals and produces lactate.
Process:
Glucose is converted to pyruvate via glycolysis.
Reduced NAD (from glycolysis) transfers hydrogen to form lactate and NAD.
NAD can be reused in glycolysis.
The production of lactate regenerates NAD.
Meaning glycolysis can take place even when little oxygen is present, so a small amount of ATP can be produced to keep some biological processes going.

Anaerobic Respiration
Lactic acid needs to be broken down:
Animals can break down in two ways:
1)Cells can convert the lactic acid back to pyruvate.
2)Liver can convert the lactic acid back to glucose.
