Step 1
Glucose enters glycolysis pathway and glycolysis yields pyruvate, then pyruvate undergoes processing.
step 2
Pyruvate processing ;releases acetylCOA which joins the citric acid cycle.
Step 3
The citric acid cycle yields 2ATP and CO2 and also releases NADH and FADH2 to electron transport chain and chemiosmosis.
Step 4
Chemiosmosis and electron transport chain yields 25 ATP molecules and H2O Oxygen enters electron transport chain and osmosis.
