What is the main biochemical function of the electron transport chain quizlet?

What is the main biochemical function of the electron transport chain quizlet?

The main purpose of the electron transport chain is to build up a surplus of hydrogen ions (protons) in the intermembrane space sp that there will be a concentration gradient compared to the matrix of the mitochondria. This will drive ATP synthase.

What is the main function of the electron transport chain?

The electron transport chain is primarily used to send protons across the membrane into the intermembrane space. This create a proton-motive force, which will drive ATP synthase in the final step of cellular respiration to create ATP from ADP and a phosphate group.

What is the electron transport chain and what are its functions?

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.

What are the main components of the electron transport chain?

The electron transport chain is also called the Cytochrome oxidase system or as the Respiratory chain. The components of the chain include FMN, Fe–S centers, coenzyme Q, and a series of cytochromes (b, c1, c, and aa3).

What is the main function of the electron transport chain and oxidative phosphorylation processes quizlet?

Solution:The coenzymes NADH and FADH₂ are oxidized by the electron transport chain, and this oxidative process is coupled to phosphorylation of ADP to form ATP. Production of ATP is the main function of the overall process.

What is the main function of a cellular respiration?

Cellular respiration releases stored energy in glucose molecules and converts it into a form of energy that can be used by cells.

What is the electron transport chain and why is it important?

The ETC is the most important stage of cellular respiration from an energy point of view because it produces the most ATP. In a series of redox reactions, energy is liberated and used to attach a third phosphate group to adenosine diphosphate to create ATP with three phosphate groups.

How does the electron transport system work?

In the electron transport chain, electrons are passed from one molecule to another, and energy released in these electron transfers is used to form an electrochemical gradient. Oxygen sits at the end of the electron transport chain, where it accepts electrons and picks up protons to form water.

What are the steps of etc?

• Step 1: Generating a Proton Motive Force.
• Step Two: ATP Synthesis via Chemiosmosis.
• Step Three: Reduction of Oxygen.
• Summary: Oxidative Phosphorylation.

What is the main function of oxidative phosphorylation?

Oxidative phosphorylation is a highly efficient method of producing large amounts of ATP, the basic unit of energy for metabolic processes. During this process electrons are exchanged between molecules, which creates a chemical gradient that allows for the production of ATP.
