How many ATP are produced in ETC?

30-32 ATP molecules
The latest studies suggest about 30-32 ATP molecules are produced in the electron transport chain.

Is ATP used in electron transport?

Electron transport is the final stage of aerobic respiration. In this stage, energy from NADH and FADH2 is transferred to ATP. During electron transport, energy is used to pump hydrogen ions across the mitochondrial inner membrane, from the matrix into the intermembrane space.

Does the ETC produce 32 or 34 ATP?

The electron transport chain is the final step of cellular respiration where 34 ATP molecules are produced.

Why is ATP 38 or 36?

During citric acid cycle, 36 ATP molecules are produced. So, all together there are 38 molecules of ATP produced in aerobic respiration and 2 ATP are formed outside the mitochondria. Thus, option A is correct.

How are 32 ATP produced?

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.

Does the electron transport chain require energy?

In broad terms, it takes energy to make energy. Coupling the electron transport chain to ATP synthesis with a hydrogen ion gradient is chemiosmosis, first described by Nobel laureate Peter D. Mitchell. This process, the use of energy to phosphorylate ADP and produce ATP is also known as oxidative phosphorylation.

Why does the electron transport chain produce the most ATP?

Electron transport chain produces an electrochemical gradient, which facilitates the synthesis of ATP by ATP synthase by chemiosmosis.

How is 34 ATP produced in ETS?

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.

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 .

Why is ATP 32 or 30?

Is it 32 or 36 ATP?

According to some 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.
