7.8: The Chemistry of NAD+ and FAD

Therefore, we need intermediates capable of undergoing electron transfer. These are the coenzymes NAD/NADH and FAD/FADH2. These coenzymes can exist in their oxidized (NAD+ and FAD) or reduced forms (NADH and FADH2). NADPH is a close derivatives of NADH that also acts as a redox couple.

Chapter 11. Cellular Respiration – Introduction to Molecular and Cell

In aerobic respiration, ATP is produced by the electron transport chain using the energy of high-energy electrons carried by NADH or FADH 2, and the final electron acceptor is an oxygen molecule. However, in some organisms and under some conditions, ATP can be produced in the absence of oxygen.

Biofundamentals @ UC Boulder

How does the cell use the energy stored in NADH and FAD H 2 to make ATP? The answer came from the work of an eccentric British scientist, Peter Mitchell. It is known as the chemiosmotic hypothesis. Mitchell proposed that the energy held in NADH and FAD H 2 was used to generate a concentration gradient of H + across the plasma membrane in

Metabolic Energy

Many tasks that a cell must perform, such as movement and the synthesis of macromolecules, require energy. A large portion of the cell''s activities are therefore devoted to obtaining energy from the environment and using that energy to drive energy-requiring reactions. Although enzymes control the rates of virtually all chemical reactions within cells, the equilibrium

Understanding the Role of NADH in Cellular Respiration

NADH plays a crucial role in cellular respiration, a series of metabolic reactions that convert glucose into adenosine triphosphate (ATP), the primary energy currency of cells. During cellular respiration, NADH donates electrons to the electron transport chain, driving the production of ATP. This energy transfer powers various cellular functions.

Why is ATP a good energy storage molecule?

ATP is an excellent energy storage molecule to use as "currency" due to the phosphate groups that link through phosphodiester bonds. These bonds are high energy because of the associated electronegative charges exerting a repelling force between the phosphate groups.

Redox Reactions. Cells conserve energy in the form of ATP by coupling its synthesis to the release of energy via oxidation-reduction (redox) reactions, where electrons are passed from an electron donor to an electron acceptor.The oxidation of a molecule refers to the loss of its electrons, while the reduction of a molecule refers to its gain of electrons.

How does atp store and release energy?

Adenosine triphosphate (ATP) consists of an adenosine molecule bonded to three phophate groups in a row. In a process called cellular respiration, chemical energy in food is converted into chemical energy that the cell can use, and stores it in molecules of ATP. This occurs when a molecule of adenosine diphosphate (ADP) uses the energy released during
