Which Metabolic Pathway is Common to Both Cellular Respiration and Fermentation

Question

Which metabolic pathway is common to both cellular respiration and fermentation?
A) the oxidation of pyruvate to acetyl CoA
B) the citric acid cycle
C) oxidative phosphorylation
D) glycolysis
E) chemiosmosis

Accepted Answer

Glycolysis is the metabolic pathway that is common to both cellular respiration and fermentation. It is the process by which glucose is broken down into pyruvate, producing a small amount of ATP and NADH. In cellular respiration, pyruvate is further oxidized in the presence of oxygen, while in fermentation, pyruvate is converted into products like lactic acid or alcohol without the involvement of oxygen.
