What is the name of the final electron acceptor in the electron transport chain?

oxygen
At the end of the electron transport system, two protons, two electrons, and half of an oxygen molecule combine to form water. Since oxygen is the final electron acceptor, the process is called aerobic respiration.

What is the final product of the electron transport chain?

The end products of electron transport are NAD+, FAD, water and protons. The protons end up outside the mitochondrial matrix because they are pumped across the cristal membrane using the free energy of electron transport.

What is the final acceptor of electrons in the electron transport quizlet?

Oxygen is the final electron acceptor, and it has the highest affinity for electrons. When oxygen accepts an electron, it is reduced to water.

Which of the following is final e − acceptor in photosynthesis?

The final electron acceptor is NADP. In oxygenic photosynthesis, the first electron donor is water, creating oxygen as a waste product.

What is the final product of ETC quizlet?

H2O (water) is formed as a final product of the electron transport chain.

What is produced at the end of the second electron transport chain in photosynthesis?

NADP+ molecules
At the end of a short second electron transport chain, NADP+ molecules in the stroma pick up the high-energy electrons and H+ ions at the outer surface of the thylakoid membrane to become NADPH. As electrons are passed through the electron transport chain, they lose energy. 1.

Which molecule is the final electron acceptor quizlet?

Oxygen is the final electron acceptor after the electron has moved through the electron transport chain.

What is the final acceptor for its electrons during fermentation What is the final acceptor for its elections during respiration?

[9.5 – 1] The final acceptor for its electrons during fermentation is a derivative of pyruvate, such as acetaldehyde during alcohol fermentation, or pyruvate itself during lactic acid fermentation. The final acceptor for electrons during aerobic respiration is oxygen.

Which molecule is the final hydrogen acceptor in electron transport chain?

Oxygen
Oxygen is final acceptor of hydrogen.

Which of the following is final e − acceptor in photosynthesis a FNR B NADP ⊕ C PS ID co2?

NADP is the ultimate electron acceptor.

What are the final products of the electron transport chain and oxidative phosphorylation?

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.

What is produced during the electron transport chain quizlet?

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. In this stage, the electron carriers NADH and FADH2 that were produced in the Krebs cycle are ready to donate their energy to produce ATP.

What are the steps in the electron transport chain?

The major steps are 1. activation of an electron donor, from glycolysis , lipolysis, or other metabolites that feed into the Krebs cycle , 2. stepwise removal of electrons to form NADH , 3. eventual oxidation to CO2 and H2O.

What is the formula for electron transport chain?

The electron transport or respiratory chain gets its name from the fact electrons are transported to meet up with oxygen from respiration at the end of the chain. The overall electron chain transport reaction is: 2 H + + 2 e + + 1/2 O 2—> H 2 O + energy

What is the function of the electron transport chain?

Electron Transport Chain is the primary source of ATP production in the body.

  • Four protein complexes act as proton pumps that help in the synthesis of ATP.
  • Complex I pumps four protons (H+) from the mitochondrial matrix to the intermembrane space and establishes a proton gradient.

    • What happens during the 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 .
