Is NADH a protein?
No, NADH is not a protein. It is a coenzyme that plays a key role in cellular respiration by carrying high-energy electrons from one reaction to another.
Describe the role of fermentation in the second stage of cellular respiration?
In the second stage of cellular respiration, fermentation helps to regenerate NAD+ from NADH molecules produced during glycolysis. This allows glycolysis to continue producing ATP in the absence of oxygen. Fermentation can occur in the cytoplasm of cells and involves the partial breakdown of glucose to produce energy.
What is the role of NADH in cellular respiration?
Within the context of cellular respiration (as well as in photosynthesis) NADH acts as an electron receptor. During glycolysis and the Kreb's cycle, various molecules are oxidized (lose electrons) and these electrons are passed to NADH. The NADH then carries the electrons to the mitochondria where they are deposited for the electron transport chain which uses the movement of the electrons to generate ATP (adenosine triphosphate; the body's energy molecule).
What are the energy carriers of cellular respiration?
The energy carriers of cellular respiration are molecules such as ATP (adenosine triphosphate) and NADH (nicotinamide adenine dinucleotide). These molecules store and transport energy within the cell for various cellular processes. ATP is the primary energy currency of the cell, while NADH plays a crucial role in transferring electrons during the process of oxidative phosphorylation.
What are some important questions to ask about cellular respiration?
Some important questions to ask about cellular respiration include: How does cellular respiration produce energy for cells? What are the different stages of cellular respiration and how do they work? What role do mitochondria play in cellular respiration? How is cellular respiration related to the process of photosynthesis? What factors can affect the efficiency of cellular respiration in cells?
What is the full name of the coenzyme that plays a crucial role in cellular respiration and is commonly abbreviated as NADH?
The full name of the coenzyme commonly abbreviated as NADH is Nicotinamide Adenine Dinucleotide. It plays a crucial role in cellular respiration.
Is NAD reduced or oxidized to NADH during cellular respiration?
NAD is reduced to NADH during cellular respiration.
Is NAD reduced to NADH during cellular respiration?
Yes, NAD is reduced to NADH during cellular respiration.
Is NADH reduced to NAD during cellular respiration?
Yes, NADH is oxidized to NAD during cellular respiration.
Does cellular respiration use NADPH as its electron carrier?
No. Cellular respiration uses NADH as an electron carrier. NADPH is used in photosynthesis.
What is the major role of oxidative phosphorylation in cellular respiration?
To produce ATP from the high energy electron carriers NADH and FADH2.
Is NADH a protein?
No, NADH is not a protein. It is a coenzyme that plays a key role in cellular respiration by carrying high-energy electrons from one reaction to another.

In the second stage of cellular respiration, fermentation helps to regenerate NAD+ from NADH molecules produced during glycolysis. This allows glycolysis to continue producing ATP in the absence of oxygen. Fermentation can occur in the cytoplasm of cells and involves the partial breakdown of glucose to produce energy.
Where are NADH and FAHD from cellular respiration produced?
NADH is produced in the mitochondria during the citric acid cycle and the electron transport chain of cellular respiration. FADH2 is also produced in the mitochondria during the citric acid cycle.
What is electron carrier use to transfer energy in cellular respiration?
NADH.
This is the electron carrier in cellular respiration?
In most cases iron shift between ferrous and ferric states to carry and transport electrons in cellular respiration. The cytochrome b and c complexes also play a major role. In aerobic organisms, oxygen is the final electron acceptor in cellular respiration.
What phase(s) of cellular respiration produce(s) NADH H?
NADH is produced during two phases of cellular respiration: glycolysis and the citric acid cycle (Krebs cycle). In glycolysis, one molecule of NADH is generated for each glucose molecule processed. Additionally, during the citric acid cycle, multiple NADH molecules are produced as acetyl-CoA is oxidized. These NADH molecules play a crucial role in the electron transport chain, contributing to ATP production.
