Based on the figure above, use an electron tower to figure out the difference in the electrical potential if (a) DH is NADH and A is O2, and (b) DH is NADH and A is NO 3 - . Which pairs (A or B) provide the most amount of usable energy?

One molecule of ATP (or an equivalent) is produced per each turn of the cycle. The electron transport chain is the portion of aerobic respiration that uses free oxygen as the final electron acceptor for electrons removed from the intermediate compounds in glucose catabolism.

In the case of photosynthesis, light energy is converted into chemical energy, which photoautotrophs use to build carbohydrate molecules. However, autotrophs only use a few specific components of sunlight.

When we breath, air including molecular oxygen is brought into our lungs from outside of the body, the oxygen then becomes reduced, and waste products, including the reduced oxygen in the form of water, are exhaled.

A lot of energy is lost to the environment as heat. The story of life is a story of energy flow - its capture, its change of form, its use for work, and its loss as heat. The cells of living things power their activities with the energy-carrying molecule ATP. The cells of most living things make ATP from glucose in the process of cellular respiration. This process occurs in three sta

The basic concept is that oxidation of NADH, being highly exergonic, can generate the energy needed to phosphorylate ADP. Since oxidation of NADH by oxygen can potentially release 52 kCal/mol, and the energy needed to phosphorylate ATP is approximately 7.5 kCal/mol, we should be able to expect the formation of several ATP per oxidized NADH.
