How does NAD plus get oxidized?
NAD+ gets oxidized by accepting electrons (and protons) during redox reactions. It is reduced to NADH when it accepts these electrons.
What major photosynthesis reactions use water?
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.
The substance that accepts electrons from another substance is the?
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.
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 is known about the number of protons vs the number of electrons?
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.
What is the coenzyme in the of photosynthesis?
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.

What is the coenzyme accepting the majority of the hydrogens in aerobic respiration?
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.
The substance that accepts electrons from another substance is the?
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.
What is the name of the coenzyme that carries high-energy hydrogens during the process of respiration?
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.
Why is an atom which accepts an electron called reduced instead of oxidized?
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.
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 is the equation for cathodic reaction?
During electrolysis a cation moves towards cathode where it accepts the electrons and becomes reduced. M+ + e- ------> M
What happens when NAD is reduced in a biological system?
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.
What picks up energized electrons from reactions in the thylakoids of plants during photosynthesis?
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.
What is known about the number of protons vs the number of electrons?
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.
