c
If oxygen is present, production of acetyl-CoA, the citric acid cycle, and electron transport chain follow in order. If no oxygen is present, either lactic acid fermentation or alcoholic fermentation follows.
In cellular respiration, the steps following glycolysis depend on whether oxygen is present.
Select the BEST explanation:
a
Regardless if oxygen is present or not, the production of acetyl-CoA, the citric acid cycle, and electron transport chain follow in order.
b
If oxygen is present, production of acetyl-CoA, the citric acid cycle, and electron transport chain follow in order. If no oxygen is present, photosynthesis occurs starting with Photosystem II.
c
If oxygen is present, production of acetyl-CoA, the citric acid cycle, and electron transport chain follow in order. If no oxygen is present, either lactic acid fermentation or alcoholic fermentation follows.
d
In the presence of oxygen, carbon fixation occurs during the Calvin cycle, when a carbon atom from atmospheric carbon dioxide is added to a 5-carbon sugar.
