Which yields the most ATP?

Explanation: The stage of cellular respiration that produces the most ATP is the electron transport chain because out of the three stages it produce 34 ATP molecules whereas Glycolysis and the Krebs cycle do not produce very much.

Subsequently, question is, is NADH 2.5 or 3 ATP? To pass the electrons from NADH to last Oxygen acceptor,total of 10 protons are transported from matrix to inter mitochondrial membrane. 4 protons via complex 1,4 via complex 3 and 2 via complex 4. Thus for NADH— 10/4=2.5 ATP is produced actually. Similarly for 1 FADH2, 6 protons are moved so 6/4= 1.5 ATP is produced.

Also question is, which of the three steps of cellular respiration yields the most ATP?

Glycolysis produces two ATP molecules, and the Krebs cycle produces two more. Electron transport begins with several molecules of NADH and FADH2 from the Krebs cycle and transfers their energy into as many as 34 more ATP molecules.

How is 36 ATP produced?

Cellular respiration produces 36 total ATP per molecule of glucose across three stages. Breaking the bonds between carbons in the glucose molecule releases energy. There are also high energy electrons captured in the form of 2 NADH (electron carriers) which will be utilized later in the electron transport chain.

What produces ATP?

Most of the ATP in cells is produced by the enzyme ATP synthase, which converts ADP and phosphate to ATP. ATP synthase is located in the membrane of cellular structures called mitochondria; in plant cells, the enzyme also is found in chloroplasts.

How many ATP are made in the electron transport chain?

34 ATP

How many ATP are made in glycolysis?

2 ATP

How many ATP are produced in glycolysis and TCA cycle?

2

Is glycolysis aerobic or anaerobic?

Glycolysis, as we have just described it, is an anaerobic process. None of its nine steps involve the use of oxygen. However, immediately upon finishing glycolysis, the cell must continue respiration in either an aerobic or anaerobic direction; this choice is made based on the circumstances of the particular cell.

How do you replenish ATP?

One method of providing more ATP is to break down another stored chemical containing a high-energy phosphate bond so that the energy released by its breakdown can be used to reconstitute ATP from ADP and Pi: PC (creatine . 010 PO3−) decomposes to creatine plus a phosphate ion plus energy.

What is the net gain of ATP during glycolysis?

Overall, the process of glycolysis produces a net gain of two pyruvate molecules, two ATP molecules, and two NADH molecules for the cell to use for energy.

What are the end products of the electron transport chain?

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 ATP used for?

The Adenosine triphosphate (ATP) molecule is the nucleotide known in biochemistry as the “molecular currency” of intracellular energy transfer; that is, ATP is able to store and transport chemical energy within cells. ATP also plays an important role in the synthesis of nucleic acids.

How many total molecules of ATP are produced during cellular respiration?

38

What are the three products of cellular respiration?

Oxygen and glucose are both reactants in the process of cellular respiration. The main product of cellular respiration is ATP; waste products include carbon dioxide and water.

Why is ATP 38 or 36?

Calculations giving 36-38 ATP per glucose are based on the assumption that oxidation of NADH produces 3 ATP and oxidation of UQH2 (FADH2, Succinate) produces 2 ATP. They translocate protons outward across the inner mitochondrial membrane, and the resulting proton gradient is used by the ATP synthase to produce ATP.

Why does 1 NADH make 3 ATP?

NADH produces 3 ATP during the ETC (Electron Transport Chain) with oxidative phosphorylation because NADH gives up its electron to Complex I, which is at a higher energy level than the other Complexes. The electron moves again to Complex IV and again pumps more electrons across the membrane.

How many ATP are produced in TCA cycle?

Through two rounds of the citric acid cycle this generates 6 NADH, 2 FADH2, and 2 ATP total. After oxidative phosphorylation, this is 24 ATP total. As such glucose generates 38 ATP total, a fraction of the ATP is generated from fatty acids.
