glycolysis is first step common in both aerobic and anaerobic type of respiration. It occurs in cytosol
in this a glucose is converted into 2 molecules of pyruvate. it occurs in absence of oxygen
if its anaerobic respiration pyruvate will under go fermentation
if its aerobic respiration pyruvate molecule will enter in kreb cycle which occurs in mitochondrial matrix. in this NADPH2 FADPH2 is produced.
finally electron transport chain(inner mitochondrial membrane) in which oxygen molecule receives the protons from NADPH2 FADPH2 and generate ATP
