O

Answer 1

Aerobic and anaerobic respiration both initiate with glycolysis, which is the breakdown of glucose that doesn't require oxygen. The electron transport chain is not used in anaerobic respiration, while aerobic respiration produces more ATP and involves the mitochondria.

Step-by-step explanation:

Both aerobic respiration and anaerobic respiration start with the common process of glycolysis, which is the breakdown of glucose. Glycolysis is an anaerobic process and does not require oxygen. Therefore, it is a stage shared between aerobic and anaerobic respiration. However, while aerobic respiration proceeds to the Krebs cycle and electron transport chain in the presence of oxygen, producing a significant amount of ATP, anaerobic respiration occurs in the absence of oxygen and follows a different pathway that produces less ATP. Notably, aerobic respiration occurs in the mitochondria, whereas anaerobic processes such as fermentation may occur in the cytoplasm.

Additionally, it is important to clarify that only aerobic respiration ends with the electron transport chain; anaerobic respiration does not use this final stage of cellular respiration.
