What purpose do NAD+ and FADH serve in the cellular respiration process? (1 point) Responses NAD+ and FADH are the portions of the cell in which the cellular respiration process occurs. N A D + and FADH are the portions of the cell in which the cellular respiration process occurs. NAD+ and FADH are molecules that allow cellular respiration to occur in the absence of oxygen. N A D + and FADH are molecules that allow cellular respiration to occur in the absence of oxygen. NAD+ and FADH are coenzymes that carry electrons from the reduction process into the electron transport chain. N A D + and FADH are coenzymes that carry electrons from the reduction process into the electron transport chain. NAD+ and FADH are molecules that break down complex carbohydrates into the simple sugars needed for cellular respiration.
