How many ATP molecules are formed in respiration?

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 is ATP 36 or 38?

In eukaryotic cells, the theoretical maximum yield of ATP generated per glucose is 36 to 38, depending on how the 2 NADH generated in the cytoplasm during glycolysis enter the mitochondria and whether the resulting yield is 2 or 3 ATP per NADH.

Does cellular respiration make 36 or 38 ATP?

ATP yield during aerobic respiration is not 36–38, but only about 30–32 ATP molecules / 1 molecule of glucose . 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 synthase produces 1 ATP / 3 H+.

How ATP is formed during respiration?

As electrons move down the chain, energy is released and used to pump protons out of the matrix, forming a gradient. Protons flow back into the matrix through an enzyme called ATP synthase, making ATP. At the end of the electron transport chain, oxygen accepts electrons and takes up protons to form water.

How is 34 ATP produced?

The Krebs cycle takes place inside the mitochondria. The Krebs cycle produces the CO₂ that you breath out. 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.

Where is 36 ATP produced?

During respiration, 36 ATP molecules are produced per glucose molecule. 2 molecules of ATP are produced outside mitochondria i.e., during glycolysis and other 34 molecules of ATP are produced inside mitochondria from Krebs cycle.

How is 36 ATP formed in aerobic respiration?

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).

How many ATP are produced in glycolysis?

During glycolysis, glucose ultimately breaks down into pyruvate and energy; a total of 2 ATP is derived in the process (Glucose + 2 NAD+ + 2 ADP + 2 Pi --> 2 Pyruvate + 2 NADH + 2 H+ + 2 ATP + 2 H2O). The hydroxyl groups allow for phosphorylation. The specific form of glucose used in glycolysis is glucose 6-phosphate.

How many ATP are produced in glycolysis and TCA cycle?

In glycolysis net production of 2 ATP. Krebs cycle production is 1 ATP(1 molecule of GTP) and with ETS total production is 12Atp.

How do we get 32 ATP?

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 are produced in anaerobic respiration?

Thus, the ATP molecules produced in anaerobic respiration is 2 ATP.

How many ATP are produced from 1 NADH?

In cytoplasm, one molecule of NADH is equivalent to 2 ATP. Inside the mitochondria, one molecule of NADH is equivalent to 3 ATP.

Does the ETC produce 32 or 34 ATP?

In fact, 34 ATP are produced. The ETC is directly aerobic because it uses oxygen and converts it into water.

Which process produces 32 36 ATP molecules?

The process human cells use to generate ATP is called cellular respiration. It results in the creation of 36 to 38 ATP per molecule of glucose.

How up to 32 36 molecules of ATP are produced for each glucose molecule?

Electron transport from the molecules of NADH and FADH₂ made from glycolysis, the transformation of pyruvate, and the Krebs cycle creates as many as 32 more ATP molecules. Therefore, a total of up to 36 molecules of ATP can be made from just one molecule of glucose in the process of cellular respiration.
