Which of the following substances is a product of stage 2 of aerobic cellular respiration? Group of answer choicesFADHwaterATPcarbon dioxide

The product of stage 2 of aerobic cellular respiration, also known as the Krebs cycle or citric acid cycle, is ATP, FADH, carbon dioxide, and water. However, the main product that is directly used by the cells is ATP (adenosine triphosphate). ATP is the energy currency of the cell and is used to power various cellular processes. FADH and NADH, which are also produced, are used in the next stage of cellular respiration (the electron transport chain) to produce even more ATP. Carbon dioxide is a waste product that is exhaled by the organism. Water is also produced in the electron transport chain.
