During Aerobic Respiration Electrons Travel in Which Sequence?

In summary, most electrons use the “downhill” path during cellular respiration: glucose NADH electron transport chain oxygen.

You might also be thinking, What happens to electrons in aerobic respiration?

The electron transport chain, also known as the “respiratory chain,” is embedded in the inner membrane of the mitochondria for aerobic respiration (see figure below). The high-energy electrons are donated to energy carrier molecules inside the membrane by the FADH2 and NADH molecules created during glycolysis and the Krebs Cycle. 13.08.2020

Similarly, How the electrons move between molecules in aerobic respiration?

Electrons are transmitted from one molecule to the next in the electron transport chain, and the energy released during these electron transfers is utilised to create an electrochemical gradient. The energy stored in the gradient is utilized to create ATP in chemiosmosis.

But then this question also arises, Which of the following correctly describes the sequence in which electrons move downhill during aerobic respiration?

“glucose – NADHelectron transport – O2″ is the right sequence for electron downward transportation during cellular respiration (b is.

What happens during electron transport?

Electrons are transmitted from one molecule to the next in the electron transport chain, and the energy released during these electron transfers is utilised to create an electrochemical gradient. The energy stored in the gradient is utilized to create ATP in chemiosmosis.

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

– A proton gradient is created across the mitochondrial membrane. The intermembrane gap of mitochondria is where protons accumulate. – The creation of water and the reduction of molecular oxygen. – Chemiosmosis ATP synthesis

What order do the electrons move through the electron transport chain?

The electrons must pass through specific proteins caught in the thylakoid membrane to get to their destination. They go along the electron transport chain, passing via the first unique protein (photosystem II protein). Then they pass through a second protein that is unique to them (photosystem I protein).

How are electrons transported to the membrane at the beginning of the electron transport chain?

oxidative phosphorylation in a nutshell A variety of proteins located in the inner mitochondrial membrane make up the electron transport chain. NADH and FADH2 deposit electrons in the chain in the matrix (at the first and second complexes of the chain, respectively).

How do electrons move in the electron transport chain?

Electrons are transmitted from one molecule to the next in the electron transport chain, and the energy released during these electron transfers is utilised to create an electrochemical gradient. The energy stored in the gradient is utilized to create ATP in chemiosmosis.

What happens to the oxygen that is used in aerobic cellular respiration?

During aerobic cellular respiration, glucose combines with oxygen to generate ATP, which the cell may utilise. Byproducts include carbon dioxide and water. The general equation for aerobic cellular respiration is: glucose and oxygen react to create ATP in cellular respiration.

Which pathway do most electrons follow inside an active mitochondrion?

KVPY. – All India Exams.

Which of the following sequences correctly represents the flow of electrons during photosynthesis?

As a result, the correct answer is ‘H20 NADPH Calvin Cycle.’

Which of the following is the correct sequence of events in cellular respiration?

What is the proper order of cellular respiration events? Glycolysis, preliminary process, citric acid cycle, and electron transport chain are the right answers. 20.12.2021

What are the stages of aerobic respiration?

Aerobic respiration is a set of enzyme-controlled events that allow living organisms to access the energy stored in carbohydrates and lipids during photosynthesis. Glycolysis, the link reaction, the Krebs cycle, and oxidative phosphorylation are the four phases.

What happens during the electron transport stage of cellular respiration?

The last step of the respiration route is the electron transport chain. It is the stage in which the most ATP molecules are produced. The electron transport chain is a group of carrier proteins present on mitochondria’s inner membrane. The hydrogen ions and electrons are released into the transport chain by NADH.

What are the 5 steps of the electron transport chain?

– NADH and FADH transport electrons 2 is the start of the subscript, and 2 is the end of the subscript. – Proton pumping and electron transfer – Oxygen splitting to make water. – ATP synthesis based on gradients.

What is complex 4 in the electron transport chain?

The electron transport chain’s Complex IV, commonly known as cytochrome c oxidase, is a multiunit structure that transfers electrons from cytochrome c to oxygen, forming water in the process and assisting in the generation of a proton gradient.

What is the final electron acceptor where does the electron acceptor travel to next?

Explanation: In the electron transport chain, oxygen is the ultimate electron acceptor, allowing for oxidative phosphorylation.

What is the order for the flow of electrons through the electron transport chain in mitochondria quizlet?

Electron carriers transfer electrons across the electron transport chain. Electrons travel from NADH via complex 1 to Q in complex III in complex I. Complex II electrons go from succinate to FADH2 and then to Q in complex III.

In which stage of photosynthesis does electron transport begin?

The electron flow channel begins at photosystem II, which is similar to the previously characterized photosynthetic reaction center of R. viridis. Photosystem II, on the other hand, uses the energy obtained from photon absorption to break water molecules into molecular oxygen and protons (see Figure 10.22).

What is the correct sequence of electron acceptor in ATP synthesis?

As a result, the proper electron acceptor order in ATP production is Cyt. b, c, a, a3.
