Question

lactic acid fermentation and aerobic respiration. glycolysis and anaerobic respiration. alcohol fermentation and anaerobic respiration. glycolysis and aerobic respiration.

Explanation:

Cellular respiration has two main parts: glycolysis, which is the first - stage breakdown of glucose, and aerobic respiration which occurs in the presence of oxygen and produces a large amount of ATP. Anaerobic respiration (including lactic acid fermentation and alcohol fermentation) is an alternative pathway when oxygen is scarce, but it is not one of the two main parts of cellular respiration in the general sense.

Answer:

glycolysis and aerobic respiration.
