Answer;
-Electron transport chain
Explanation;
-Electron transport is one of the steps of cellular respiration. Electron carriers are reduced during glycolysis and the citric acid cycle to NADH + H+ and FADH2. These carriers then donate electrons and protons to the electron carrier proteins of the electron transport chain.
-About 38 ATP molecules can be made per oxidized glucose molecule during cellular respiration that is; 2 ATP molecules from glycolysis, 2 ATP from the Krebs cycle, and about 34 ATP from the electron transport system.
