Does glycolysis have steps involving oxidation-reduction reactions?
Yes, glycolysis involves several oxidation-reduction reactions. For example, the conversion of glyceraldehyde-3-phosphate to 1,3-bisphosphoglycerate involves the oxidation of NAD+ to NADH. This process helps to generate energy in the form of ATP.
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.
How does the conversion of NAD to NADH during oxidation or reduction processes impact cellular energy production?
The conversion of NAD to NADH during oxidation or reduction processes plays a crucial role in cellular energy production. NADH carries electrons to the electron transport chain in the mitochondria, where they are used to generate ATP, the energy currency of the cell. This process, known as oxidative phosphorylation, is essential for producing the energy needed for various cellular activities.

The conversion of NAD to NADH during reduction or oxidation processes plays a crucial role in cellular energy production. NADH carries electrons to the electron transport chain in the mitochondria, where they are used to generate ATP, the main energy currency of the cell. This process, known as oxidative phosphorylation, is essential for producing the energy needed for various cellular activities.
Is fermentation an oxidation or a reduction process?
Fermentation is not considered as an oxydation reaction. ------------------------------------------------------------------ It may not usually be considered as such, but the oxidation state of C in sugar is zero, and the oxidation state of C in ethanol is -2. Any change in oxidation state can be treated as a redox process. Loss of electrons (or an increase of oxidation state) is oxidation, gain of electrons (or a decrease of oxidation state) is reduction. The carbon that ends up in the ethanol has decreased its oxidation state from 0 to -2 so those atoms have undergone reduction. Reduction cannot exist without a subsequent oxidation, so something else has undergone oxidation. The fermentation process also makes carbon dioxide. The C in those molecules has an oxidation state of +4, so those atoms of carbon have been oxidized. So the answer is --- both.

Why does nad become nadh plus h instead of just nadh during glycolysis?
During glycolysis, NAD+ acts as an electron carrier molecule. It accepts two electrons and a proton to form NADH. This is important for the oxidation-reduction reactions that occur during glycolysis, allowing for the transfer of electrons and the generation of ATP.
What enzyme would use NAD as a coenzyme?
Alcohol dehydrogenase uses NAD as a coenzyme to catalyze the conversion of alcohols to aldehydes or ketones, with the reduction of NAD+ to NADH.
What happens that causes hadh to change to nad plus and fadh2 to change to fad?
Loss of electrons causes NADH to become NAD+. This cycle of oxidation reduction helps generate ATP in cell respiration.
What happens when NAD plus becomes NADH?
When NAD+ is reduced to NADH, it accepts two electrons and a hydrogen ion, becoming a carrier of high-energy electrons. This conversion usually occurs during cellular respiration where NADH is a key player in transferring electrons to the electron transport chain for ATP production.
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.
How is dehydrogenase involved in the reduction of coenzyme NADH during cellular respiration?
Dehydrogenase enzymes catalyze the removal of hydrogen atoms from molecules like NADH during cellular respiration. This process results in the oxidation and reduction of substrates, allowing the energy released to be used to make ATP. The reduced coenzyme NADH carries the electrons to the electron transport chain to produce ATP in aerobic cellular respiration.
What does the conversion of lactic acid to pyruvic acid require?
NADH
