What is the role of the electron transport chain in cellular respiration?

The electron transport chain is the last stage of the respiration pathway. It is the stage that produces the most ATP molecules. The electrons transfer their energy to the proteins in the membrane providing the energy for hydrogen ions to be pumped across the inner mitochondrial membrane.

What is electron transport chain explain?

The electron transport chain is a cluster of proteins that transfer electrons through a membrane within mitochondria to form a gradient of protons that drives the creation of adenosine triphosphate (ATP).

What are the 3 main steps of the electron transport chain?

The three main steps in the electron transport chain are:

• Generation of a proton gradient across the mitochondrial membrane. Proton accumulation occurs in the intermembrane space of mitochondria.
• Reduction of molecular oxygen and formation of water.
• ATP synthesis by chemiosmosis.

What is electron transport Class 11?

Electron transport system (ETS) is the metabolic pathway through which the electron passes from one carrier to another. It is located in the inner mitochondrial membrane. These electrons are then transferred to ubiquinone which is located within the inner membrane.

What processes use electron transport?

The electron transport chain (aka ETC) is a process in which the NADH and [FADH2] produced during glycolysis, β-oxidation, and other catabolic processes are oxidized thus releasing energy in the form of ATP. The mechanism by which ATP is formed in the ETC is called chemiosmotic phosphorolation.

What is electron transport chain BYJU’s?

Electron Transport Chain is a series of compounds where it makes use of electrons from electron carrier to develop a chemical gradient. The electrons are transferred from electron donor to the electron acceptor leading to the production of ATP. It is one of the vital phases in the electron transport chain.

What is electron transport chain and oxidative phosphorylation?

Oxidative phosphorylation is a process involving a flow of electrons through the electron transport chain, a series of proteins and electron carriers within the mitochondrial membrane. This flow of electrons allows the electron transport chain to pump protons to one side of the mitochondrial membrane.

What is an electron transport chain What is its role during the light reactions?

What is its role during these light reactions? An electron transport chain is a series of electron-transport molecules. To capture energy & use it to pump more hydrogen ions into the thylakoid interior space.
