Why is O2 the final electron acceptor?
The final electron acceptor is oxygen (O2). Oxygen has a high electronegativity; thus, oxygen’s high affinity for electrons makes it an ideal acceptor for low-energy electrons. With the electrons, hydrogen is added to oxygen forming water as the final product.

What is the final electron acceptor in cellular respiration quizlet?
Final electron acceptor in cellular respiration is oxygen. Oxygen accepts electrons at the end of the electron transport chain and facilitates recycling of N A D + NAD^+ NAD+ and enables the chain to progress.

Is NADH the final electron acceptor in cellular respiration?
In aerobic respiration, the final electron acceptor is an oxygen molecule, O2. If aerobic respiration occurs, then ATP will be produced using the energy of the high-energy electrons carried by NADH or FADH2 to the electron transport chain.

What is the first electron acceptor of cellular respiration?
The reactants of cellular respiration vary at each stage, but initially, it requires an input of glucose, ATP, and NAD+. NAD+, a nicotinamide derived from vitamin B3, is a universal electron acceptor that is crucial in the process of cellular respiration.

What is the final electron acceptor of cellular respiration?
Oxygen is the final electron acceptor in this respiratory cascade, and its reduction to water is used as a vehicle by which to clear the mitochondrial chain of low-energy, spent electrons. The enzyme that catalyzes this process, cytochrome oxidase, spans the mitochondrial membrane.

Is NADH an electron donor or acceptor?
NADH is a strong electron donor: because its electrons are held in a high-energy linkage, the free-energy change for passing its electrons to many other molecules is favorable (see Figure 14-9). It is difficult to form a high-energy linkage. Therefore its redox partner, NAD+, is of necessity a weak electron acceptor.

What is the final acceptor of electrons from NADH and FADH2?
The electron transport in the inner membrane of the mitochondria is a series of protein complexes that receive electrons from NADH and FADH2. Transferring electrons through the protein complexes results in the pumping of protons into the inner membrane space, and the final acceptor is oxygen, generating water.

What is the electron acceptor in cellular respiration?
Explanation: In cellular respiration, oxygen is the final electron acceptor. Oxygen accepts the electrons after they have passed through the electron transport chain and ATPase, the enzyme responsible for creating high-energy ATP molecules.

Is NAD an electron acceptor in cellular respiration?
NAD + (Nicotinamide adenine dinucleotide) is a coenzyme found in all cells. It is an electron carrier used to temporarily store energy during cellular respiration. This is found in two forms in cells: NAD+ is an oxidizing agent – it accepts electrons from other molecules and becomes reduced.

What is meant by the concept of the final electron acceptor?
A final electron acceptor is a molecule that accepts electrons last in an electron transport chain (ETC). For example, the final electron acceptor of the electron transport chain in mitochondria is oxygen. Oxygen accepts electrons from the different protein complexes of the ETC.
