What happens to the 2 ATP molecules made in glycolysis?
What happens to the 2 ATP molecules made in glycolysis?
Step 2. In the second step of glycolysis, an isomerase converts glucose-6-phosphate into one of its isomers, fructose-6-phosphate. A second ATP molecule donates a high-energy phosphate to fructose-6-phosphate, producing fructose-1,6-bisphosphate.
What is the end product of ATP?
The by-products of the breakdown of ATP are adenosine diphosphate (ADP), which is the remaining adenosine and two (di) phosphate groups, and one single phosphate (Pi) that is ‘on its own’.
Is the process that yields 2 ATP molecules each in the first and second stages of cellular respiration?
Glycolysis produces 2 ATP molecules, and the Krebs cycle produces 2 more. Electron transport begins with several molecules of NADH and FADH2 from the Krebs cycle and transfers their energy into as many as 34 more ATP molecules.
What is the total number of ATP molecules that can be produced from the complete oxidation of one glucose molecule?
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.
Why the number of ATP is not known exactly?
The total number of ATP is not known exactly and is due to variance in the degree of coupling between the flow of protons through the ATPase and electron transport. ATP – Adenosine triphosphate, the energy currency of the cell are organic compounds composed of the phosphate groups, adenine and sugar ribose.
Why does lack of oxygen result in the halt of ATP synthesis?
Why does lack of oxygen result in the halt of ATP synthesis? The chain shuts down and can no longer pump hydrogen ions across the membrane, and the proton gradient cannot be maintained. This causes the proton gradient to break down, stopping ATP synthesis.
Why do prokaryotes make more ATP per glucose?
Complete answer: In prokaryotes, there are no mitochondria, the whole process of respiration occurs within the cytoplasm so no ATP is consumed in transporting across the organelle. Therefore, 38 ATPs are made from one glucose in bacteria while 36 are made in a eukaryotic cell.
Where do prokaryotes produce the majority of their ATP?
Answer and Explanation: ATP is generated in the plasma membrane of prokaryotic cells.
What is the number of ATP produced in aerobic respiration?
36 ATP
What stage of aerobic respiration requires ATP?
Glycolysis
Which stage of aerobic respiration produces the most ATP?
electron transport system
Where is the sun’s energy stored in glucose?
chloroplasts
Which sugar is stored as energy?
The sugar (glucose) is stored as starch or glycogen. Energy-storing polymers like these are broken down into glucose to supply molecules of ATP.
