What Is The Main Purpose Of The Electron Transport Chain Quizlet? - Fixanswer

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 happens in the electron transport chain quizlet?

The electron transport chain is a process that

moves hydrogen ions across a membrane to produce large amounts of ATP

. … The electron transport chain cranks out large amounts of ATP—in fact, it produces most of the ATP that a cell needs to drive all of its processes.

What is the purpose of the electron transport chain in cellular respiration quizlet?

What is the function of the electron transport chain in cellular respiration? The electron transport chain

shuttles electrons down a series of redox reactions that release energy used to make ATP.

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.

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 type of reaction does the electron transport chain perform quizlet?

A chemical reaction involving the transfer of one or more electrons from one reactant to another; also called

oxidation-reduction reaction

.

What is the final product of the electron transport chain quizlet?

H2O (water)

is formed as a final product of the electron transport chain.

What is the function of ATP synthase in the electron transport chain quizlet?

Enzyme that synthesizes ATP. ATP is mainly produced in the mitochondria and is an important enzyme that

provides energy for the cell to use through the synthesis of adenosine triphosphate

(ATP). You just studied 26 terms!

How does the electron transport chain function in the synthesis of ATP?

The electron transport chain is a series of proteins embedded in the inner mitochondrial membrane. … Protons flow down their concentration gradient into the matrix through the membrane protein ATP synthase, causing it to spin

(like a water wheel) and catalyze conversion of ADP to ATP

.

What is the role of oxygen in the electron transport chain?

Oxygen plays a vital role in energy production via a system called electron transport chain (ETC), which is an important component of cellular respiration. … Oxygen acts

as a final electron acceptor that helps move electrons down a chain

that results in adenosine triphosphate production.

Which step in cellular respiration is the electron transport chain quizlet?

The electron transport chain is

the first step in cellular respiration

. NADH and FADH2 donate their electrons to the chain. Electrons gain energy as they move down the chain. Water is the last electron acceptor.

What is the electron transport chain also known as?

The respiratory chain

, otherwise known as the electron transport chain, resides in the mitochondria. … The chain consists of a series of electron carriers which can accept and then donate electrons, while the resulting production of energy is used to stimulate the formation of ATP via oxidative phosphorylation.

What are the major events of the electron transport chain?

The events of the electron transport chain involve

NADH and FADH, which act as electron transporters as they flow through the inner membrane space

. In complex I, electrons are passed from NADH to the electron transport chain, where they flow through the remaining complexes. NADH is oxidized to NAD in this process.

Does the electron transport chain require oxygen?

Explanation:

Oxygen is the final electron acceptor in the electron transport chain

, which allows for oxidative phosphorylation. Without oxygen, the electrons will be backed up, eventually causing the electron transport chain to halt.

What are the steps in the electron transport chain?

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