Q

what happens after glycosis?

A

the 2 pyruvate molecules are reduced by gaining a hydrogen from reduced NAD to form ethanol and CO2 (in plants) or lactate (in animals). this then oxidises NAD so it can be recycled in glycosis.

even less than aerobic, because only 2 ATP molecules are produced from 1 glucose molecule, instead of 4
