# How many ATP is produced by NADH?

3 ATPs

See further detail related to it here. Beside this, is NADH 2.5 or 3 ATP?

Why does one molecule of NADH produce 2.5ATP and not 3 ATP? – Quora. If you know the electron transport chain and the ATP synthesis by ATPase (membrane bound enzyme) ,then I will answer in short. 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.

One may also ask, how many molecules of ATP NADH and fadh2 are produced per glucose? Thus, the total energy yield from one whole glucose molecule (2 pyruvate molecules) is 6 NADH, 2 FADH2, and 2 ATP.

Keeping this in view, how many ATP are produced from the 10 NADH that are formed during the citric acid cycle?

The citric acid cycle generates 3 molecules of NADH, 1 molecule of FADH2, and 1 molecule of GTP(ATP) per acetyl-sCoA that enters the cycle. Thus, in total, from each round of the citric acid cycle approximately 10 molecules of ATP are produced.

## Why is ATP 38 or 36?

Calculations giving 3638 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.

How many ATP are used in the electron transport chain?

Electron transport chain

This stage produces most of the energy ( 34 ATP molecules, compared to only 2 ATP for glycolysis and 2 ATP for Krebs cycle). The electron transport chain takes place in the mitochondria. This stage converts the NADH into ATP.

### How do you calculate ATP?

There is a theoretical maximum of 38 ATP produced from a single glucose molecule: 2 NADH produced in glycolysis (3 ATP each) + 8 NADH produced in Krebs cycle (3 ATP each) + 2 FADH2 produced I don’t know where (2 ATP each) + 2 ATP produced in the Krebs cycle + 2 ATP produced in glycolysis = 6 + 24 + 4 + 2 + 2 = 38 ATP,

### How 36 ATP is 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.

### How is 38 ATP formed?

Most of the ATP produced by aerobic cellular respiration is made by oxidative phosphorylation. Biology textbooks often state that 38 ATP molecules can be made per oxidized glucose molecule during cellular respiration (2 from glycolysis, 2 from the Krebs cycle, and about 34 from the electron transport system).

### Why does 1 NADH make 2.5 ATP?

To pass the electrons from NADH to last Oxygen acceptor,total of 10 protons are transported from matrix to inter mitochondrial membrane. 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.

### What is ATP yield?

ATP Yield. In a eukaryotic cell, the process of cellular respiration can metabolize one molecule of glucose into 30 to 32 ATP. The process of glycolysis only produces two ATP, while all the rest are produced during the electron transport chain.

### How many ATP does GTP produce?

The net gain of high-energy compounds from one cycle is 3 NADH, 1 FADH2, and 1 GTP; the GTP may subsequently be used to produce ATP. Thus, the total yield from 1 glucose molecule (2 pyruvate molecules) is 6 NADH, 2 FADH2, and 2 ATP.

### How are 32 ATP produced?

Out of the cytoplasm it goes into the Krebs cycle with the acetyl CoA. It then mixes with CO2 and makes 2 ATP, NADH, and FADH. From there the NADH and FADH go into the NADH reductase, which produces the enzyme. From the electron transport chain, the released hydrogen ions make ADP for an end result of 32 ATP.

### What is the net gain of ATP during glycolysis?

Glucose is the source of almost all energy used by cells. Overall, glycolysis produces two pyruvate molecules, a net gain of two ATP molecules, and two NADH molecules.

### 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 ATP are produced from NADH and fadh2?

Why do NADH and FADH2 produce 3 ATPs and 2 ATPs respectively? 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.

### How many NADH is produced in glycolysis?

2 NADH
