How do you calculate ATP yield?

Start by letting n = number of carbons. Additionally, 1 propionyl-CoA (3-carbon Acetyl-CoA) is produced in the last round. Based on a yield of 3 ATP per NADH and 2 ATP per FADH2 that are oxidized in the respiratory chain: Multiply the number of rounds by 3, then multiply by 2: take its sum.

Correspondingly, how is 36 ATP produced?

First off, let’s divide the 36 ATP into three parts — ATP that comes from glycolysis, and ATP that comes from the Krebs Cycle and the Electron Transport Chain. Glycolysis is the process that breaks down the 6-carbon glucose into 3-carbon pyruvate, which is a substrate for the link reaction.

Also, how much ATP does a 12 carbon fatty acid produce? Assuming Lauric acid (12:0), then 78 ATP First, it costs 2 ATP to add CoA to the fatty acid, giving lauroyl-CoA.

Consequently, what is the total yield of ATP from cellular respiration?

30 or 32 ATP Although there is a theoretical yield of 38 ATP molecules per glucose during cellular respiration, such conditions are generally not realized because of losses such as the cost of moving pyruvate (from glycolysis), phosphate, and ADP (substrates for ATP synthesis) into the mitochondria.

What is the gross ATP yield?

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 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.

Why do we use 36 ATP instead of 38?

Cellular respiration has a potential to produce between 36 and 38 moles of ATP per mole of glucose (C6H12O6). Each NADH [from glycolysis] produces a net 1.5 ATP (instead of usual 2.5) due to NADH transport over the mitochondrial membrane.

How many ATP are used in glycolysis?

2 ATP

What is the net number of ATP and NADH used?

ATP yield Stage Direct products (net) Ultimate ATP yield (net) Pyruvate oxidation 2 NADH 5 ATP Citric acid cycle 2 ATP/GTP 2 ATP 6 NADH 15 ATP 2 FADH 2 3 ATP

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).

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.

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.

Is it 36 or 38 ATP?

The amount of energy contributed by glycolysis differs depending on which electron carrier (NADH or FADH2) is used to span the mitochondrial membrane. That is why the amount of ATP produced by cellular respiration is estimated to be between 36 and 38 moles.

Does aerobic respiration produce 36 or 38 ATP?

According to some of newer sources the ATP yield during aerobic respiration is not 36–38, but only about 30–32 ATP molecules / 1 molecule of glucose , because: ATP : NADH+H+ and ATP : FADH2 ratios during the oxidative phosphorylation appear to be not 3 and 2, but 2.5 and 1.5 respectively.

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 in TCA cycle?

2 ATP

How 4 ATP are produced in glycolysis?

It does not require oxygen. During glycolysis, one glucose molecule is split into two pyruvate molecules, using 2 ATP while producing 4 ATP and 2 NADH molecules.

How is ATP made?

Although cells continuously break down ATP to obtain energy, ATP also is constantly being synthesized from ADP and phosphate through the processes of cellular respiration. Most of the ATP in cells is produced by the enzyme ATP synthase, which converts ADP and phosphate to ATP.

How many ATP are produced per NADH?

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.

What is the maximum theoretical yield of ATP molecules during cellular respiration?

Overall, the theoretical maximum yield of ATP made during the complete aerobic respiration of glucose is 38 molecules, with four being made by substrate-level phosphorylation and 34 being made by oxidative phosphorylation (Table 1).

What is the net gain of ATP during aerobic respiration?

During aerobic respiration, each NADH2 forms 3 ATP and water. Hence, net gain of ATP molecules in glycolysis is 2 ATP + 6 ATP = 8 ATP.

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 ATP are produced in fatty acid oxidation?

The NADH and FADH2 produced by both beta oxidation and the TCA cycle are used by the mitochondrial electron transport chain to produce ATP. Complete oxidation of one palmitate molecule (fatty acid containing 16 carbons) generates 129 ATP molecules.

How many ATP are in fatty acid synthesis?

The synthesis of palmitate requires the input of 8 molecules of acetyl CoA, 14 molecules of NADPH, and 7 molecules of ATP. Fatty acids are synthesized in the cytosol, whereas acetyl CoA is formed from pyruvate in mitochondria.
