What are the reactants and products of electron transport chain?

What are 3 reactants of the electron transport chain?

The reactants of the electron transport chain are NADH, FADH2, protons, ADP, and oxygen. NADH and FADH2 are electron carriers produced during glycolysis and the Citric Acid Cycle that donate electrons to the protein complexes in the inner membrane of the mitochondria.

Is FMN an electron carrier?

FMN is an electron carrier molecule that functions as a hydrogen acceptor.

Is NAD+ a reactant or product?

The reactants are pyruvate, NADH, and a proton. The products are lactate and NAD+. The process of fermentation results in the reduction of pyruvate to form lactic acid and the oxidation of NADH to form NAD+. Electrons from NADH and a proton are used to reduce pyruvate into lactate.

What is the largest byproduct of the electron transport chain?

The mechanism by which ATP is formed in the ETC is called chemiosmotic phosphorolation.

• Introduction. The byproducts of most catabolic processes are NADH and [FADH2] which are the reduced forms.
• Overview.
• Electron Flow.
• Proton Motive Force.

What are the two main products of the electron transport chain?

The end products of the electron transport chain are water and ATP. A number of intermediate compounds of the citric acid cycle can be diverted into the anabolism of other biochemical molecules, such as nonessential amino acids, sugars, and lipids.

Is acetyl CoA a reactant or product?

The only reactants of the Krebs cycle proper are acetyl CoA and the aforementioned four-carbon molecule, oxaloacetate.

Is co2 a reactant in glycolysis?

The answer is C, carbon dioxide only. Glucose is a reactant of cellular respiration (and of glycolysis, the first step), while the others are intermediates along the way from deriving a total of 36 to 38 ATP from glucose so long as oxygen is present.

What is a waste product of the electron transport chain?

Through electron transport chain, most of the energy from glucose is converted into ATP. Oxygen is the final acceptors of electrons in ETC and forms water as it combines with hydrogen ions. Carbon dioxide is produced as a waste product.

What molecules supply electrons to an electron transport chain?

The electron transport chain involves a series of redox reactions that relies on protein complexes to transfer electrons from a donor molecule to an acceptor molecule. As a result of these reactions, the proton gradient is produced, enabling mechanical work to be converted into chemical energy, allowing ATP synthesis.

What are the end products of the electron transport chain?

The major end products of the electron transport chain are. A. water, carbon dioxide and ATP. B. glucose and amino acids. C. dietary fiber and ammonia. D. carbon, nitrogen and hydrogen.

What product is made by the electron transport chain?

Much of the ATP created by the electron transport chain is made by a chemiosmotic gradient, an area in which high concentrations of hydrogen ions give way to lower concentrations. The chain aids in production of this gradient, although other cellular processes contribute to and maintain it.
