What would happen to NADH levels in a cell in the first few seconds after a drug has poisoned the enzyme that converts acetyl CoA to citrate?
NADH levels would increase in the cell due to the build-up of acetyl CoA, as it cannot be converted to citrate. This is because the enzyme responsible for converting acetyl CoA to citrate is inhibited, leading to a block in the tricarboxylic acid (TCA) cycle and subsequent accumulation of NADH.
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.
Should I take NAD or NADH for my health and well-being?
NAD is generally recommended for health and well-being as it is the active form of the coenzyme involved in various cellular processes, while NADH is the reduced form and may not be as effective.
What is the ATP conversion for one NADH?
One NADH molecule generates approximately 2.5 to 3 ATP through oxidative phosphorylation in the mitochondria.
How do you recycle NADH to NAD?
NADH can be recycled to NAD through the process of oxidative phosphorylation in mitochondria. During this process, NADH donates its electrons to the electron transport chain, leading to the generation of ATP and the conversion of NADH back to NAD+.
How does malonate inhibit NADH?
Malonate inhibits NADH by competing with NAD+ for binding to the active site of enzyme NADH dehydrogenase within the electron transport chain. This competition prevents NADH from donating electrons to the enzyme, disrupting the flow of electrons and inhibiting ATP production.
Enzyme in all steps of respiration?
NADH

What accompanies the conversion of pyruvate to acetyl CoA in preparation for the citric acid cycle?
The conversion of pyruvate to acetyl CoA involves the release of carbon dioxide, the reduction of NAD+ to NADH, and the formation of a two-carbon acetyl group that binds to coenzyme A. This process occurs in the mitochondrial matrix and is catalyzed by the enzyme pyruvate dehydrogenase complex.
If you were to make a flowchart about enzymes which of these terms would go first apoenzyme active site calcium enzyme chloride nadh coenzyme haloenzymeholoenzyme zinc ck-mb isoenymes?
Km values for lactate dehydrogenase -1,2,3,4,5.
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.
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.
What is the significance of the NADH absorbance spectrum in biochemical analysis?
The NADH absorbance spectrum is important in biochemical analysis because it provides information about the concentration and activity of NADH, a key molecule involved in cellular energy production. By measuring the absorbance spectrum of NADH, scientists can study metabolic processes, enzyme activity, and overall cellular health.
What is the role of enzyme complex in the electron transport chain?
A. Transfer electrons to NAD+ B. Power Krebs cycle C. Receive electrons from NADH D. Produce ATP from sugar
What is the significance of NADH absorbance at 340 nm in biochemical assays?
The absorbance of NADH at 340 nm is significant in biochemical assays because it can be used to measure the activity of enzymes that utilize NADH as a cofactor. By monitoring the changes in absorbance at 340 nm, researchers can track the conversion of NADH to its oxidized form, NAD, which provides valuable information about enzyme kinetics and metabolic processes.
Should I take NAD or NADH for my health and well-being?
NAD is generally recommended for health and well-being as it is the active form of the coenzyme involved in various cellular processes, while NADH is the reduced form and may not be as effective.
What is equation for lactic acid after glycolysis?
The equation for the production of lactic acid after glycolysis is pyruvate + NADH + H+ -> lactate + NAD+. This reaction is catalyzed by the enzyme lactate dehydrogenase.
