FAD, or flavin adenine dinucleotide, is a crucial coenzyme in cellular respiration that acts as an electron carrier. It is involved primarily in the Krebs cycle (citric acid cycle) and the electron transport chain, where it helps to transport electrons and protons, facilitating ATP production. When FAD accepts electrons, it is reduced to FADH2, which later donates these electrons to the electron transport chain, contributing to the generation of ATP through oxidative phosphorylation.

What terminal electron acceptors are used in anaerobic cellular respiration?
anaerobic cellular respiration has 3 different stages, and their final electron acceptors are: pyruvate oxidation- NAD+ Krebs cycle- NAD+, FAD+ electron transport chain- Oxygen
How many ATP do you get after cellular respiration?
ATP is used for cellular respiration. It is not a product of cellular respiration.
Why is external respiration vital to cellular respiration?
Cellular respiration need oxygen. This oxygen is supplied by external respiration
What is the process by which the chemical energy of food molecules is released?
The first step of the process is the digestion.
Is cellular respiration a physical property?
Cellular respiration is a biochemical process.
What are two examples of coenzymes used in cellular respiration?
Two examples of coenzymes used in cellular respiration are NAD+ (nicotinamide adenine dinucleotide) and FAD (flavin adenine dinucleotide). These coenzymes accept and carry electrons during the process of respiration, allowing for the production of ATP.
What molecules serve as intermediate electron carriers in the process of cellular respiration?
NAD+ (nicotinamide adenine dinucleotide) and FAD (flavin adenine dinucleotide) serve as intermediate electron carriers in cellular respiration. They accept electrons from the breakdown of glucose and transfer them to the electron transport chain for the production of ATP.
What hydrogen carriers are used in cellular respiration?
NAD and FAD are the two hydrogen carriers involved in respiration. NAD is reduced in glycolysis, the Link Reaction and the Krebs Cycle to NADH + H+; whilst FAD is reduced to FADH2 solely in the Krebs Cycle. The role of the hydrogen carriers is to transport the hydrogen atoms to the Electron Transport Chain, where their energy is used to join ADP and Pi to give a molecule of ATP.
What terminal electron acceptors are used in anaerobic cellular respiration?
anaerobic cellular respiration has 3 different stages, and their final electron acceptors are: pyruvate oxidation- NAD+ Krebs cycle- NAD+, FAD+ electron transport chain- Oxygen
What factors affect the rate of cellular respiration?
Factors that affect the rate of cellular respiration include temperature, concentration of reactants (such as glucose and oxygen), availability of enzymes, and pH levels. These factors influence the activity of enzymes involved in the various stages of cellular respiration, ultimately impacting the overall rate of the process.
FAD stands for in cell analogy?
In a cell analogy, FAD stands for Flavine Adenine Dinucleotide. It is a coenzyme that plays a crucial role in cellular respiration by accepting and donating electrons during the formation of ATP.
How many ATP do you get after cellular respiration?
ATP is used for cellular respiration. It is not a product of cellular respiration.
What acts as an electron carrier in cellular respiration?
NAD+ (nicotinamide adenine dinucleotide) and FAD (flavin adenine dinucleotide) are electron carriers in cellular respiration. They accept electrons and hydrogen ions from molecules during the process of converting food into energy.
How is anaerobic respiration different from cellular respiration?
Anaerobic respiration does not require oxygen, while cellular respiration does. Anaerobic respiration produces less energy compared to cellular respiration.
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 are the difference cellular respiration and respiration?
Oxygen is the difference! Cellular respiration requires oxygen, while cellular fermentation does not.
Why is cellular respiration an aerobic respiration?
Because cellular respiration occurs in the presence of oxygen.
