Expert Answer

The process in which glucose is broken down to pyruvate is called glycolysis. It takes in the cytoplasm.

The process by which pyruvate is broken down to ethanol along with the release of energy is called fermentation. It takes place in mitochondria.

Both glycolysis and fermentation are a part of the life process respiration.

Differences between respiration and combustion:

RESPIRATION	COMBUSTION
Occurs in a series of chemical steps	Occurs in a single step
Carried out by enzymes	Carried out by heat
Biochemical process	Physicochemical process
Energy is liberated in the form of ATP and some heat	Energy is liberated in the form of heat and light
No light energy is produced	Light energy is produced
Slow process	Fast process
