in the course of the krebs cycle, how many molecules of atp are produced

Full Answer

What is produced during the Krebs cycle?

The steps in the Krebs cycle are:

• The TCA cycle starts with an enzymatic aldol addition reaction of acetyl CoA to oxaloacetate, which results in the formation of citrate.
• A dehydration-hydration sequence is used to isomerize citrate, yielding (2R,3S)-isocitrate.
• 2-ketoglutarate is formed after more enzymatic oxidation and decarboxylation.

What are two of the products of the Krebs cycle?

These molecules are:

• 4 ATP (including 2 from glycolysis)
• 10 NADH (including 2 from glycolysis)
• 2 FADH 2

What are the by-products of the Krebs cycle?

So, for every 1 pyruvate molecule added, the Krebs cycle will produce: 2 molecules of CO 2 3 molecules of NADH 1 molecule of FADH 2 1 molecule of GTP

What does the Krebs cycle produce during one turn?

A molecule of carbon dioxide was produced. Throughout the Krebs cycle, energy is transferred to other high potential energy molecules. List those molecules and indicate the number produced with one "turn" of the cycle. 1 ATP molecule, 3 NADH molecules, and one FADH2 molecule.

How many ATP are produced in the Krebs cycle?

two ATPIn the Krebs cycle, two ATP, six NADH +H+, and two FADH2 were produced. A net of four ATPs was produced from glycolysis through the Krebs cycle. More ATP will be produced from reduced coenzymes in the mitochondria during the electron transport chain and oxidative phosphorylation.

Is 38 ATP produced in Krebs cycle?

-Inside the mitochondria, the Krebs cycle occurs. The TCA (Tri Carboxylic Acid) cycle or citric acid cycle will occur inside the inner mitochondrial membrane. -During the complete process of aerobic respiration the total number of ATP molecules produced are 38.

Does Kreb Cycle produce 34 ATP?

There are multiple stages of cellular respiration, each with their own ATP output. One of the stages, glycolysis makes a net 2 ATP molecules. Another stage, the Krebs cycle makes a net 2 ATP molecules. The most productive stage, the electron transport chain makes 32 or 34 ATP molecules.

How 36 or 38 ATP are formed?

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.

Why is ATP 36 or 38?

Explanation for Correct option: The citric acid cycle produces 36 ATP molecules. So, in aerobic respiration, a total of 38 molecules of ATP are created, with 2 ATP molecules formed outside the mitochondria.

How are 34 ATP molecules produced in the electron transport chain?

One molecule of NADH produces 3 molecules of ATP and one molecule of FADH2 produce 2 molecules of ATP. In ETS 10 NADH molecules are produced while 2 FADH2 molecules are formed. Therefore, the total ATP generated from these NADH and FADH2 molecules is 34 molecules.

How is 34 ATP formed?

Electrons from NADH and FADH2 are then transferred to molecular oxygen, coupled to the formation of an additional 32 to 34 ATP molecules by oxidative phosphorylation.

Why do eukaryotes only produce 36 ATP?

Both prokaryotes and eukaryotes produce the same amount of ATP which is thought to be 38 ATPs. Some textbooks state that the net yield is 36 ATPs in eukaryotes because 2 ATPs are used up to power cellular respiration itself in moving 2 NADH molecules into a mitochondrian (38 ATPs - 2 ATPs = 36 ATPs).

How Many ATP Are Produced in the Krebs Cycle? - Reference.com

The Krebs cycle produces two molecules of ATP for every molecule of glucose. The Krebs cycle also produces eight molecules of NADH and two molecules of FADH2 per molecule of glucose. NADH and FADH2 are later used to produce energy during electron transport phosphorylation.

Answer

Krebs cycle or also known as Tricarboxylic acid cycle (TCA) is the second stage of aerobic cellular respiration which occurs in the mitochondria. In the kreb cycle, pyruvate, which was synthesized in the first stage of cellular respiration (glycolysis) is broken down into carbon dioxide (CO2).
