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.
What does nadh mean in science?
NADH (nicotinamide adenine dinucleotide) is a coenzyme found in cells that plays a crucial role in the process of cellular respiration. It serves as an electron carrier, helping to transfer electrons from one molecule to another during the production of ATP, the cell's main energy source. NADH is produced during the breakdown of sugars and fats in the cell.
What is the A340 value for NADH?
The millimolar extinction coefficient of NADH at 340 nm is approximately 6.22 mM-1 cm-1.
How does the conversion of NADH to NAD during reduction or oxidation processes impact cellular energy production?
The conversion of NADH to NAD during reduction or oxidation processes is crucial for cellular energy production. NADH carries electrons to the electron transport chain, where they are used to generate ATP, the energy currency of the cell. By regenerating NAD through this process, cells can continue to produce ATP and sustain their energy needs.
What is the significance of NADH absorbance in biochemical assays?
NADH absorbance is significant in biochemical assays because it can be used to measure the activity of enzymes involved in cellular respiration. Changes in NADH absorbance indicate the conversion of NADH to NAD by enzymes, providing valuable information about metabolic processes and enzyme function.
During cell respiration what is the purpose of NADH?
NADH is a coenzyme that carries electrons from glucose molecules through the electron transport chain in the mitochondria. These electrons are used to generate ATP, the cell's primary energy source, through a process called oxidative phosphorylation.
What is the point which glucose is completely oxidized during cellular respiration?
Glucose is completely oxidized after chemiosmosis because that's when the final products of Glycolysis and The Citric Acid Cycle are used creating the final 36 to 38 ATP molecules. The final products that are used are NADH and FADH2 which are needed in the electron transport chain and ultimatley Chemiosmosis. Hope i answered your question.
Are NADH FADH used to carry high energy electrons and H?
Is lactic acid formed and muscle tissue when there is not enough oxygen present
Where does the energy of the proton gradient go?
The energy of the proton gradient in the mitochondria is used by ATP synthase to generate ATP from ADP and inorganic phosphate through a process known as chemiosmosis. This ATP production is a key step in cellular respiration and provides the cell with the energy it needs to carry out its various functions.
Where else in chloroplasts does chemiosmosis translocates protons from?
Protons are translocated from the stroma to the thylakoid lumen in chloroplasts during chemiosmosis. This creates a proton gradient that is used by ATP synthase to generate ATP through the process of photophosphorylation.
When NADH loses a hydrogen ion?
It becomes NAD. This happens during electron transport where NADH drops off its H+ and electrons to be used in oxidative phosphorylation. NAD now must move to glycolysis or citric acid cycle to regain its hydrogen.
How is most most of the ATP from aerobic respiration produced?
The majority of ATP is produced in oxidative phosphorylation. This process has two main components, the electron transport chain and chemiosmosis. Chemiosmosis is a process where hydrogen ions act like water threw a turbine pushing ATP synthase.
What is the sugar used in glycolysis?
Glucose is the sugar used in glycolysis. It is broken down into pyruvate during the process, generating ATP and NADH in the cytoplasm of cells.
What coenzyme is used to carry electrons in redox reactions?
A coenzyme called NAD is used to carry electrons in different kinds of redox reactions. NAD stands for nicotinamide adenine dinucleotide.
What molecule is produced with the expenditure of nadh fermentation?
Lactate is produced in this way. It is a product of the NADH fermentation.

What produces ATP nadh and co2?
The process of cellular respiration in mitochondria produces ATP, NADH, and CO2. During glycolysis and the citric acid cycle, glucose is broken down to produce NADH and carbon dioxide. The electrons carried by NADH are used in the electron transport chain to generate ATP through oxidative phosphorylation.
