What is the electron transport chain and what is its function?

The electron transport chain is a series of electron transporters embedded in the inner mitochondrial membrane that shuttles electrons from NADH and FADH2 to molecular oxygen. In the process, protons are pumped from the mitochondrial matrix to the intermembrane space, and oxygen is reduced to form water.

Beside above, how do you explain the electron transport chain?

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). ATP is used by the cell as the energy for metabolic processes for cellular functions.

Consequently, 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.

Likewise, what is the electron transport chain for kids?

An electron transport chain (ETC) is how a cell gets energy from sunlight in photosynthesis. Electron transport chains also occur in reduction/oxidation (“redox”) reactions, such as the oxidation of sugars in cellular respiration.

What is the electron transport chain simplified?

What is the electron transport chain used for?

The electron transport chain is used to pump protons into the intermembrane space. This establishes a proton gradient, allowing protons to be pumped through ATP synthase in order to create ATP. This method of ATP production is called oxidative phosphorylation.

What is the meaning of electron transport?

Definition of electron transport

: the sequential transfer of electrons especially by cytochromes in cellular respiration from an oxidizable substrate to molecular oxygen by a series of oxidation-reduction reactions.
