In glycolysis of cellular respiration, NADH produces 2ATP because one ATP is used to transport a molecule of NADH into the mitochondria and continue with aerobic respiration. However, in pyruvate decarboxylation and the Krebs cycle, each NADH yields 3ATPs. FADH2 yields 2 ATPs.
What else can I help you with?
How much energy does glycolysis produce?
Glycolysis produces a net gain of 2 ATP molecules and 2 NADH molecules per glucose molecule. Each ATP molecule provides about 7.3 kilocalories of energy.
How many ATP and NADH molecules are produced from each molecule of glucose in the citric acid cycle only?
In my textbook it says that 1 molecule of ATP and 3 molecules of NADH are made from 1 molecule of pyruvate, via the citric acid cycle. However, since the question is asking for 1 molecule of GLUCOSE, the answer would be 2 ATP and 6 NADH since the oxidation of glucose produces TWO molecules of pyruvate, the amount of ATP and NADH would have to be doubled. I actually have this EXACT question on my exam... hmmm... do I know you by chance? o__O
What are the Products of the Krebs cycle per molecule of pyruvate?
For one molecule of Pyruvate (pyruvic acid) the Krebs cycle produces 2 molecules of carbon dioxide (CO2), 3 molecules of NADH, one molecule of FADH2, and one molecule of ATP.Also, the change from pyruvate to acetyl CoA produces one NADH and one carbon dioxide molecule; CoA is recycled in and out of the cycle.
In glycolysis for each molecule of glucose oxidized to pyruvate?
Two molecules of ATP are consumed in the energy investment phase, while four molecules of ATP and two molecules of NADH are produced in the energy payoff phase. This results in a net gain of two molecules of ATP per molecule of glucose oxidized to pyruvate.
What cycle produces the most NADH?
Electron Transport Chain. It produces 32 while the citric acid cycle (your teacher might call it the Krebs Cycle) produces 2 and glycolysis produces 2 (all those numbers are per ONE GLUCOSE MOLECULE) Electron Transport Chain. It produces 32 while the citric acid cycle (your teacher might call it the Krebs Cycle) produces 2 and glycolysis produces 2 (all those numbers are per ONE GLUCOSE MOLECULE)
How many nadh and fadh are produced from Krebs cycle?
During one turn of the Krebs cycle (also known as the citric acid cycle or TCA cycle), three molecules of NADH and one molecule of FADH2 are produced. Since each glucose molecule yields two acetyl-CoA molecules, the overall yield from one glucose molecule is six NADH and two FADH2. These electron carriers are then utilized in the electron transport chain to generate ATP.
How many glucose moleculeswere broken down if 2NADH molecules were produced?
If 2 NADH molecules were produced in glycolysis, it means that 1 glucose molecule was broken down. Each glucose molecule yields 2 NADH molecules during glycolysis.
How much energy does glycolysis produce?
Glycolysis produces a net gain of 2 ATP molecules and 2 NADH molecules per glucose molecule. Each ATP molecule provides about 7.3 kilocalories of energy.

How many fadh are produced in the bridge reaction?
In the bridge reaction, also known as the transition step between glycolysis and the Krebs cycle, one molecule of pyruvate is converted into one molecule of acetyl-CoA. During this process, one molecule of NADH is produced for each pyruvate converted. Since each glucose molecule produces two pyruvate molecules, a total of two NADH molecules are generated from the bridge reaction for each glucose molecule. However, no FADH2 is produced in this step.
What phase(s) of cellular respiration produce(s) NADH H?
NADH is produced during two phases of cellular respiration: glycolysis and the citric acid cycle (Krebs cycle). In glycolysis, one molecule of NADH is generated for each glucose molecule processed. Additionally, during the citric acid cycle, multiple NADH molecules are produced as acetyl-CoA is oxidized. These NADH molecules play a crucial role in the electron transport chain, contributing to ATP production.
What are the Products of the Krebs cycle per molecule of pyruvate?
For one molecule of Pyruvate (pyruvic acid) the Krebs cycle produces 2 molecules of carbon dioxide (CO2), 3 molecules of NADH, one molecule of FADH2, and one molecule of ATP.Also, the change from pyruvate to acetyl CoA produces one NADH and one carbon dioxide molecule; CoA is recycled in and out of the cycle.
Are 2 ATPs formed per NADH?
No, 2 ATPs are not formed per NADH. In cellular respiration, each NADH molecule typically generates approximately 2.5 ATPs through oxidative phosphorylation in the electron transport chain. This value can vary slightly depending on the specific conditions within the cell, but 2.5 ATPs is the commonly accepted yield for NADH.
How many NAD molecules are needed for the breakdown of each glucose molecule?
Two NAD+ molecules are needed for the breakdown of each glucose molecule during glycolysis. NAD+ is reduced to NADH during certain reactions in glycolysis, allowing it to carry electrons to the electron transport chain for further energy production.
In glycolysis for each molecule of glucose oxidized to pyruvate?
Two molecules of ATP are consumed in the energy investment phase, while four molecules of ATP and two molecules of NADH are produced in the energy payoff phase. This results in a net gain of two molecules of ATP per molecule of glucose oxidized to pyruvate.
How many ATP are produces during the bridge reactions?
During the bridge reactions, also known as the pyruvate decarboxylation process, no ATP is directly produced. Instead, this process converts pyruvate into acetyl-CoA while generating one molecule of NADH for each pyruvate molecule, which can later be used to produce ATP in the electron transport chain. Since each glucose molecule yields two pyruvate molecules, this results in two NADH molecules per glucose, contributing to ATP production indirectly.
What cycle produces the most NADH?
Electron Transport Chain. It produces 32 while the citric acid cycle (your teacher might call it the Krebs Cycle) produces 2 and glycolysis produces 2 (all those numbers are per ONE GLUCOSE MOLECULE) Electron Transport Chain. It produces 32 while the citric acid cycle (your teacher might call it the Krebs Cycle) produces 2 and glycolysis produces 2 (all those numbers are per ONE GLUCOSE MOLECULE)
