NADH is a crucial electron carrier in both cellular respiration and photosynthesis. In cellular respiration, it is produced during glycolysis and the citric acid cycle, where it stores energy by transferring electrons to the electron transport chain, ultimately leading to ATP production. In photosynthesis, NADH is generated in the light-dependent reactions and used in the Calvin cycle to help convert carbon dioxide into glucose, thereby linking energy capture to carbon fixation. Both processes highlight NADH's role in energy metabolism and the transfer of electrons.
What else can I help you with?
Does cellular respiration use NADPH as its electron carrier?
No. Cellular respiration uses NADH as an electron carrier. NADPH is used in photosynthesis.
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.
Is the etc in both cellular respiration and photosynthesis?
Yes, the electron transport chain (ETC) is involved in both cellular respiration and photosynthesis. In cellular respiration, the ETC is located in the inner mitochondrial membrane and is responsible for producing ATP by transferring electrons from NADH and FADH2 through a series of protein complexes. In photosynthesis, the ETC occurs in the thylakoid membranes of chloroplasts, where it helps convert light energy into chemical energy, ultimately leading to the production of ATP and NADPH. Both processes highlight the importance of the ETC in energy transformation within cells.
What phase of cellular respiration produces Nada h?
NADH is produced during both the glycolysis and citric acid cycle phases of cellular respiration. In glycolysis, NADH is generated when glucose is broken down into pyruvate. In the citric acid cycle, NADH is produced as acetyl-CoA is further metabolized to generate ATP.
What is one true distinction between fermentation and cellular respiration?
cellular respiration uses oxygen but fermentation does not use oxygen
Does cellular respiration use NADPH as its electron carrier?
No. Cellular respiration uses NADH as an electron carrier. NADPH is used in photosynthesis.
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.
What are two high energy electron carriers used in cellular respiration that are not used in photosynthesis?
Two high energy electron carriers used in cellular respiration that are not used in photosynthesis are NADH (Nicotinamide Adenine Dinucleotide) and FADH2 (Flavin Adenine Dinucleotide). These molecules play a crucial role in transferring electrons from the breakdown of glucose to the electron transport chain in cellular respiration, ultimately leading to the production of ATP. In photosynthesis, the electron carriers NADH and FADH2 are not involved as the process uses different electron carriers such as NADPH (Nicotinamide Adenine Dinucleotide Phosphate) and ATP.
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.
What is the role of NADH in cellular respiration?
NADH plays a crucial role in cellular respiration by carrying high-energy electrons to the electron transport chain, where they are used to generate ATP, the cell's main source of energy.
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.
What part of glucose molecule provides electrons in cellular respiration?
hydrogen from the NADH and FADH2
What is the significance of NADH in cellular respiration and how does it contribute to the production of ATP?
NADH is important in cellular respiration because it carries high-energy electrons that are used to generate ATP, the cell's main energy source. During the process of cellular respiration, NADH donates these electrons to the electron transport chain, which then uses them to create a proton gradient that drives the production of ATP through a process called oxidative phosphorylation. In essence, NADH helps convert the energy stored in food molecules into ATP, which is essential for various cellular functions.
