Which of the following metabolic pathways is common to both aerobic and anaerobic metabolism?
A
Citric Acid Cycle
B
Electron Transport Chain
C
Oxidative Phosphorylation
D
Glycolysis
Verified step by step guidance1
Understand the context: Metabolic pathways are series of chemical reactions occurring within a cell. Aerobic metabolism requires oxygen, while anaerobic metabolism does not.
Identify the pathways: The Citric Acid Cycle, Electron Transport Chain, and Oxidative Phosphorylation are all part of aerobic respiration, which requires oxygen.
Recognize Glycolysis: Glycolysis is the process of breaking down glucose into pyruvate, yielding ATP and NADH, and it occurs in the cytoplasm of the cell.
Note the conditions: Glycolysis does not require oxygen, making it a part of both aerobic and anaerobic metabolism.
Conclude: Since Glycolysis occurs in both aerobic and anaerobic conditions, it is the common metabolic pathway shared by both types of metabolism.
