Which electron carrier(s) function in the krebs cycle

Nadh fadh2. Actually those are two separate processes. Phosphorylation takes place in the inner mitochondrial membrane. The Krebs cycle takes place in the mitochondrial matrix.

The electron transport chain contains three complexes and two mobile carriers. The two major stages of aerobic respiration are the krebs cycle and electron transport. They are as follows: Glycolysis, the Krebs cycle, and the electron transport chain. Source: another Wiki Answer. This happens in the breakdown of Acetyl CoA in the Krebs Cycle aka the citric acid cycle inside the second membrane of the mitochondria.

NADH and FADH2 will carry and donate the electrons to the Electron Transport Chain on the internal membrane; the transfer of the electron's energy allows for the proteins crossing the membrane to pump hydrogen ions into the space between the two membranes and build up a gradient for chemiosmosis. They are two different cycles. Only two ATP is yield of Krebs cycle. The raw materials of the Krebs cycle are the acetyl-CoA and oxaloacetate.

The first two stages of the process is called cellular respiration. Glycolysis breaks down glucose, produced by photosynthesis, into two molecules of Pyruvic Acid, which is used in the Krebs cycle.

Its main function is to build an electrochemical gradient across the inner membrane using protons. The ETC pumps hydrogen ions out of the matrix of the mitochondria and into the intermembrane space.

What is the purpose of the ETC? 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. The ETC is the most important stage of cellular respiration from an energy point of view because it produces the most ATP.

When a cell needs energy, it breaks the third phosphate group bond and uses the resulting energy. Explanation: Oxygen acts as the terminal electron acceptor in the electron transport chain ETC. 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.

Skip to content Biology. Category: science chemistry. These carriers bring their electrons to the electron transport chain, which creates a hydrogen ion gradient in intermembrane of the mitochondria. The mitochondria is the powerhouse of the cell. What is the role of oxygen in aerobic respiration? Aerobic respiration uses oxygen to break down glucose, amino acids, and fatty acids and is the main way the body generates adenosine triphosphate ATP , which supplies energy to the muscles.

Why do we need NADH? Now, we have the reduced form, or NADH. The molecule acts as a shuttle for electrons during cellular respiration. Is NADH an electron carrier? Is Oxygen an electron carrier? In aerobic respiration, the final electron acceptor for the electron transport chain is an oxygen molecule, O 2. What is the role of electrons in cellular respiration?

In cellular respiration , electrons from glucose move gradually through the electron transport chain towards oxygen, passing to lower and lower energy states and releasing energy at each step.

The goal of cellular respiration is to capture this energy in the form of ATP. What is the difference between NADH and nadh2? What is the function of fad?
