The coenzyme that accepts two protons and two electrons when reduced is NAD+ (nicotinamide adenine dinucleotide). Upon reduction, it is converted to NADH, which plays a crucial role in cellular respiration and energy production. NADH serves as an electron carrier in various metabolic processes, facilitating the transfer of electrons to the electron transport chain.
NAD+ gets oxidized by accepting electrons (and protons) during redox reactions. It is reduced to NADH when it accepts these electrons.
The light (dependent) reactions. Water is split into its components, hydrogen and oxygen. Gaseous oxygen is released as a by-product, the hydrogens are further split into protons and electrons, the electrons are use to replenish those lost by Photosystem II, and the protons are eventually picked up by NADP coenzyme. The coenzyme is reduced to NADPH, which is later utilized in the dark reactions to reduce atmospheric carbon dioxide.
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.
In a redox reaction, the substance that accepts electrons is said to be the substance reduced. This substance is also likely the oxidizing agent, since oxidation is the loss of electrons.
A key coenzyme carrier associated specifically with the Krebs cycle (citric acid cycle) is NAD+ (nicotinamide adenine dinucleotide). During the cycle, NAD+ is reduced to NADH as it accepts electrons, facilitating the transfer of energy derived from the oxidation of substrates. This process is crucial for the subsequent production of ATP during oxidative phosphorylation. Another important coenzyme in the cycle is FAD (flavin adenine dinucleotide), which also serves a similar role in electron transport and energy transfer.
The coenzyme in photosynthesis is NADP+ (nicotinamide adenine dinucleotide phosphate), which functions as an electron carrier during the light-dependent reactions. It accepts electrons from photosystem I and is reduced to NADPH, which carries the high-energy electrons to the Calvin cycle for carbon fixation.

NAD+ (nicotinamide adenine dinucleotide), which is reduced to NADH by the hydrogen. Another molecules that performs the same function but plays a relatively more minor role is FADH, which is reduced to FADH2.
In a redox reaction, the substance that accepts electrons is said to be the substance reduced. This substance is also likely the oxidizing agent, since oxidation is the loss of electrons.
The coenzyme that carries high-energy hydrogens during respiration is called nicotinamide adenine dinucleotide (NAD+). NAD+ accepts hydrogen atoms and becomes reduced to NADH, carrying the high-energy electrons to the electron transport chain for ATP production.

An atom that accepts an electron is called reduced because it gains electrons, which leads to a reduction in its oxidation state. In a reduction-oxidation (redox) reaction, the atom that accepts electrons is undergoing reduction, not oxidation.
A coenzyme called NAD is used to carry electrons in different kinds of redox reactions. NAD stands for nicotinamide adenine dinucleotide.
During electrolysis a cation moves towards cathode where it accepts the electrons and becomes reduced. M+ + e- ------> M
Nicotinamide adenine dinucleotide (NAD+) serves as a coenzyme in the Krebs cycle. It is derived from niacin (vitamin B3) and plays a crucial role in the oxidation-reduction reactions that occur during the cycle, facilitating the transfer of electrons. NAD+ is reduced to NADH, which subsequently carries electrons to the electron transport chain for ATP production.
