What is the function of the NADH/FADH2 molecules? NADH and FADH2 are molecules that play a crucial role in cellular respiration. They are electron carriers that are produced during the breakdown of glucose in the presence of oxygen. These molecules are generated in different stages of cellular respiration and are involved in the production of ATP, the energy currency of the cell. NADH is produced during glycolysis, the first step of cellular respiration, and also during the citric acid cycle, which occurs in the mitochondria. It carries high-energy electrons to the electron transport chain, where the electrons are passed along a series of protein complexes. As the electrons move through the chain, energy is released and used to pump protons across the inner mitochondrial membrane. This creates a proton gradient, which is used to generate ATP through a process called oxidative phosphorylation. FADH2 is also produced during the citric acid cycle. It carries electrons to the electron transport chain, but at a lower energy level compared to NADH. As a result, FADH2 generates less ATP than NADH. However, it still contributes to the overall production of ATP through oxidative phosphorylation. In summary, the function of NADH and FADH2 is to carry high-energy electrons to the electron transport chain, where they are used to generate ATP through oxidative phosphorylation. These molecules are essential for the efficient production of energy in the form of ATP during cellular respiration.

What is the function of NADPH, NADH, and FADH2 in photosynthesis and respiration? Group of answer choices They transport high-energy electrons to an electron transport chain. They oxidize various intermediates in cellular respiration and photosynthesis. They release energy required for glycolysis to proceed. They are used by cells as a source of chemical energy when ATP is unavailable.

What role do NADH and FADH2 serve in catabolism? NADH and FADH2 are electron carriers. NADH and FADH2 donate electrons to oxygen. NADH and FADH2 donate electrons to ATPase (ATP synthase). NADH and FADH2 pump protons across a membrane.
