what is the reactants electron transport?

The main biochemical reactants of the ETC are the electron donors succinate and nicotinamide adenine dinucleotide hydrate (NADH). These are generated by a process called the citric acid cycle (CAC). Fats and sugars are broken down into simpler molecules such as pyruvate, which then feed into the CAC.

The electron transport chain is a process that moves hydrogen ions across a membrane to produce large amounts of ATP. ... In this stage, the electron carriers NADH and FADH2 that were produced in the Krebs cycle are ready to donate their energy to produce ATP.

An electron carrier is a molecule that transports electrons during cellular respiration. ... The energy stored in NADH + H+ and FADH2 will be released later in cellular respiration to generate ATP, which can be used as an energy source throughout the cell.

A number of molecules can act as electron carriers in biological systems. In cellular respiration, there are two important electron carriers, nicotinamide adenine dinucleotide (abbreviated as NAD+ in its oxidized form) and flavin adenine dinucleotide (abbreviated as FAD in its oxidized form).

The electron transport chain is a series of protein complexes and electron carrier molecules within the inner membrane of mitochondria that generate ATP for energy. ... This movement of protons provides the energy for the production of ATP. The electron transport chain is the third step of aerobic cellular respiration.

Because any loss of electrons by one substance must be accompanied by a gain in electrons by something else, oxidation and reduction always occur together. As such, electron-transfer reactions are also called oxidation-reduction reactions, or simply redox reactions.
36565
The electron transport chain contains a number of electron carriers. These carriers take the electrons from NADH and FADH2, pass them down the chain of complexes and electron carriers, and ultimately produce ATP. ... Oxygen is required for this process because it serves as the final electron acceptor, forming water.

A redox (or oxidation-reduction) reaction is a type of chemical reaction that involves a transfer of electrons between two species. What is a "species"? We can tell there has been a transfer of electrons if there is any change in the oxidation number between the reactants and the products.
848942
Oxidation/Reduction A reaction where one element loses electrons (oxidized) from reactants to products, and another element gains electrons (reduced) from reactants to products. Single displacement and combustion reactions are ALWAYS redox. ... This will include many synthesis and decomposition reactions.

['Anode: The anode is where the oxidation reaction takes place. In other words, this is where the metal loses electrons. ... ', 'Cathode: The cathode is where the reduction reaction takes place. This is where the metal electrode gains electrons.']

Oxygen and glucose represent the reactants, while carbon dioxide, water, and energy represent the products. Reactants are the molecules that combine to start the reaction. Products are those molecules produced during cellular respiration. ... Carbohydrates are high-energy molecules that are made from glucose subunits.
200426
The reactants are oxygen and glucose. The products are ATP, CO2, and water.

An oxidizing agent, or oxidant, gains electrons and is reduced in a chemical reaction. ... A reducing agent, or reductant, loses electrons and is oxidized in a chemical reaction. A reducing agent is typically in one of its lower possible oxidation states, and is known as the electron donor.

At the end of the electron transport chain involved in aerobic respiration, the last electron carrier in the membrane transfers 2 electrons to half an oxygen molecule (an oxygen atom) that simultaneously combines with 2 protons from the surrounding medium to produce water as an end product (Figure 5).

The electron transport chain is a series of protein complexes and electron carrier molecules within the inner membrane of mitochondria that generate ATP for energy. Electrons are passed along the chain from protein complex to protein complex until they are donated to oxygen.
686020
The electron transport chain produces adenosine triphosphate, the main cellular energy. Oxygen acts as a final electron acceptor that helps move electrons down a chain that results in adenosine triphosphate production.
740970
The electrons passing through the electron transport chain gradually lose energy, High-energy electrons donated to the chain by either NADH or FADH2 complete the chain, as low-energy electrons reduce oxygen molecules and form water. ... The end products of the electron transport chain are water and ATP.
