Cellular respiration has anaerobic and aerobic. Aerobic is the normal way in which glucose enters and goes through glycolysis giving out 2 ATP, 2 NADH, 2 pyruvate. Pyruvate is converted into Acetyl CoA in the mitochondria. Once in mitochondria, O2, NADH, and Acetyl CoA is required to make 2 ATP, FADH2, NADH and CO2. The outputs of krebs cycle are inputs of ETC which finally creates 32 ATP and H2O
Anaerobic respiration goes through glycolysis but animals have lactate formed to give a final amount of 2 atp. Plants have alcohol formed in them to also make 2 ATP. The process after glycolysis is known as fermentation.
