Question

multiple choice 1 point which metabolic process is common to both aerobic cellular respiration and alcoholic fermentation? krebs cycle glycolysis electron transport chain production of a proton gradient conversion of pyruvic acid to acetyl coa

Explanation:

Glycolysis is the first - stage of both aerobic cellular respiration and alcoholic fermentation. It breaks down glucose into pyruvate and produces a small amount of ATP and NADH. The Krebs cycle and electron transport chain are only part of aerobic respiration. The conversion of pyruvic acid to acetyl - CoA occurs only in aerobic respiration after glycolysis. The production of a proton gradient is mainly associated with the electron transport chain in aerobic respiration.

Answer:

Glycolysis
