Which pathway requires oxygen as the final electron acceptor in aerobic respiration?
The electron transport chain is the pathway that requires oxygen as the final electron acceptor in aerobic respiration. Oxygen acts as the terminal electron acceptor to form water, enabling the production of ATP through oxidative phosphorylation.
What happens to pyruvate if electron acceptor is absent and What happens if electron acceptor is present?
If an electron acceptor is absent, pyruvate undergoes fermentation, resulting in the production of lactate in animals or ethanol and carbon dioxide in yeast, allowing for the regeneration of NAD+ and enabling glycolysis to continue. In contrast, if an electron acceptor is present, pyruvate enters the mitochondria and is oxidized in the citric acid cycle (Krebs cycle), leading to the production of ATP, NADH, and FADH2 through aerobic respiration. This process is more efficient in energy production compared to fermentation.
What is the terminal electron acceptor in aerobic cellular respiration?
NAD+ is the first electron acceptor in cellular respiration (O2 is the final acceptor).
What are the functions of NAD and FAD?
To oxidize the intermediate products of glycolysis and the citric acid cycle and then, in reduced state, take their electrons and hydrogens to the systems of the electron transport chain where ATP production is the ultimate result.NAD + --> NADHFAD + --> FADH2
Which is the electron acceptor in the electron transport chain?
ATP-synthase
The final electron acceptor in glycolysis is?
The final electron acceptor in glycolysis is oxygen, which is needed for the production of ATP in aerobic respiration. Oxygen captures the electrons at the end of the electron transport chain to form water.
What is the final electron acceptor of the electron transport chain that functions in aerobic oxidative phosphorylation?
oxygen
Which pathway requires oxygen as the final electron acceptor in aerobic respiration?
The electron transport chain is the pathway that requires oxygen as the final electron acceptor in aerobic respiration. Oxygen acts as the terminal electron acceptor to form water, enabling the production of ATP through oxidative phosphorylation.
What is the intermediate electron acceptor for oxidations that occur in both glycolysis and in Krebs cycle reactions?
The intermediate electron acceptor for oxidations in both glycolysis and the Krebs cycle is NAD+ (nicotinamide adenine dinucleotide). NAD+ accepts electrons and becomes reduced to NADH during these metabolic pathways. NADH can then donate its electrons to the electron transport chain for further energy production.
What is the electron acceptor for humans in the electron transport chain?
The electron acceptor for humans in the electron transport chain is oxygen.

Does hydrogen serve as the final electron acceptor of the electron transport chain?
No, oxygen is the final electron acceptor of the electron transport chain.
Is NAD an electron acceptor in biological processes?
Yes, NAD is an electron acceptor in biological processes.
The final electron acceptor of the electron transport chain that functions in oxidative phosphorylation is?
Oxygen is the final electron acceptor of the electron transport chain in oxidative phosphorylation. It accepts electrons from complex IV (cytochrome c oxidase) and combines with hydrogen ions to form water.
What is the terminal electron acceptor in aerobic cellular respiration?
NAD+ is the first electron acceptor in cellular respiration (O2 is the final acceptor).
During glycolysis NADH is formed when hydrogen atoms are transferred to an electron acceptor called?
NAD+ (Nicotinamide adenine dinucleotide) gains two hydrogen atoms and two electrons to form NADH during glycolysis. NAD+ acts as an electron carrier, accepting the hydrogen atoms and becoming reduced to form NADH.
If humans and other animals are capable of glycolysis why do you need to breathe oxygen?
the krebs cycle and electron transport chains that provide the majority of the ATP gain require oxidative phosphorilation, the oxygen plays the part of a electron acceptor at the end of the etc
