They are interchangeable energy carriers, allowing the cell to use whichever molecule is in greatest abundance as a source of energy. They both act as electron carriers in the cell. Both compounds function as mobile energy carrier molecules in a cell. Both molecules are oxidized by molecular oxygen (O2) in reactions that release energy for use by the cell. Both ATP and NADH function as reducing agents in metabolic reactions.

Not all words or phrases will be used; each word or phrase may be used more than once. ADP FADH2 H+ moderately protons ATP favorable higher NADH severely cytosol glucose lower NAD+ slightly electrons GTP matrix Pi unfavorable High-energy electrons are transferred through a series of molecules, and the energy released during these transfers is used to generate a gradient of , or . Because their concentration is outside than inside the mitochondria, the flow of , or , down the concentration gradient is energetically very and can thus be coupled to the production of ATP from ADP. Thus, oxidative phosphorylation refers to the…ATP energy is used to form NADH or NADPH. -True -False Glycolysis happens in the cytoplasm.
