In the Krebs cycle, one ATP is made per turn.
ATP, or adenosine triphosphate, is the primary energy source for most cellular processes. It is generated through a number of metabolic pathways, including the krebs cycle.
The krebs cycle, also known as the citric acid cycle, is a series of reactions that takes place in the mitochondria of cells. These reactions result in the production of ATP, as well as other important molecules such as NADH and FADH2.
So how many ATP are produced in the krebs cycle? This depends on a number of factors, including the number of cycles that are completed and the efficiency of the enzymes involved. In general, however, it is estimated that each krebs cycle produces between 2 and 10 ATP.
This may seem like a relatively small amount, but when you consider that a single cell can have hundreds or even thousands of mitochondria, the total ATP production can be quite significant. In fact, it has been estimated that the krebs cycle is responsible for the production of around 60-80% of the ATP used by cells.
So next time you’re feeling tired, just remember that your cells are working hard to produce ATP through the krebs cycle, and that this ATP is helping to keep you going!
How Many ATP Are Made In The Krebs Cycle Per Molecule Of Glucose?
In the Krebs cycle, 1 molecule of glucose is converted into 2 molecules of ATP.
ATP, or adenosine triphosphate, is the currency of energy in cells. Every time a cell needs to do something that requires energy—like contracting muscles, synthesizing proteins, or pumpsing out sodium ions against their concentration gradient—ATP is there to do the work.
ATP is made up of adenine, the sugar ribose, and three phosphate groups. When ATP breaks down into ADP (adenosine diphosphate) and Pi (inorganic phosphate), it releases a lot of energy—enough to power most of the cellular processes that keep us alive.
The Krebs cycle, also known as the citric acid cycle, is a series of reactions in cells that generate ATP. The Krebs cycle starts with acetyl-CoA, a two-carbon molecule that comes from the breakdown of glucose, and ends with four molecules of ATP, four molecules of water, and two molecules of carbon dioxide.
In between, the Krebs cycle involves a series of eight reactions that convert the acetyl-CoA into ATP, water, and carbon dioxide. These reactions occur in the mitochondria, the powerhouses of the cell.
The first step of the Krebs cycle is the conversion of acetyl-CoA into citrate, a six-carbon molecule. This reaction is catalyzed by the enzyme citrate synthase.
The next six steps involve a series of reactions that break down the citrate into water, carbon dioxide, and ATP. These reactions are catalyzed by a series of enzymes, including isocitrate dehydrogenase, α-ketoglutarate dehydrogenase, and succinate dehydrogenase.
The final step of the Krebs cycle is the conversion of succinate into fumarate, catalyzed by the enzyme succinate dehydrogenase. This reaction regenerates the molecule that started the whole cycle—acetyl-CoA—so the cycle can start again.
In total, the Krebs cycle generates four molecules of ATP, two molecules of water, and two molecules of carbon dioxide.
How Many ATP Are Made In The Krebs Cycle Per Molecule Of Acetate?
In the Krebs cycle, one molecule of acetate produces two molecules of ATP.
ATP is the energy currency of the cell, and it is produced in the Krebs cycle. One molecule of acetate can produce up to 12 molecules of ATP.
