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.
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 coenzyme called NAD is used to carry electrons in different kinds of redox reactions. NAD stands for nicotinamide adenine dinucleotide.
The number of protons in an atom determines its atomic number and identifies the element. The number of electrons in an atom is usually the same as the number of protons, which keeps the atom electrically neutral. If an atom gains or loses electrons, it becomes an ion with a net positive or negative charge.
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
When NAD is reduced in a biological system, it accepts electrons and becomes NADH. This process is important for transferring energy in cells and is a key step in cellular respiration.
The molecule that picks up energized electrons in the thylakoid membranes during photosynthesis is called NADP+ (nicotinamide adenine dinucleotide phosphate). It accepts the electrons and is reduced to NADPH, which then carries the electrons to the Calvin cycle for the production of sugars.

The number of electrons in an atom is usually the same as the number of protons, which keeps the atom electrically neutral.
