is more or less energy required to regenerate atp?
610276
Energy is required to regenerate molecules of ATP that have been broken down. ATP is regenerated by joining a molecule of ADP to a phosphate group. The breakdown and regeneration of ATP can be summarised by the diagram below.

ATP functions as the energy currency for cells. It allows the cell to store energy briefly and transport it within the cell to support endergonic chemical reactions. The structure of ATP is that of an RNA nucleotide with three phosphates attached. ... Energy derived from glucose catabolism is used to convert ADP into ATP.

The ATP molecule is just like a rechargeable battery. When it's fully charged, it's ATP. When it's run down, it's ADP. ... There are times when the cell needs even more energy, and it splits off another phosphate, so it goes from ADP, adenoside di-phosphate, to AMP, adenosine mono-phosphate.

Fermentation is less efficient at using the energy from glucose: only 2 ATP are produced per glucose, compared to the 38 ATP per glucose nominally produced by aerobic respiration.

ATP. ... What is the difference between ATP and ADP? ATP has three phosphate molecules and therefore more energy than ADP, which only has two phosphate molecules.
1045396
When one molecule of ATP is used in the contraction process, it is hydrolyzed to ADP, adenosine diphosphate, and an inorganic phosphate. ... In the process of regeneration of ATP, creatine phosphate transfers a high-energy phosphate to ADP. The products of this reaction are ATP and creatine.

When the cell has extra energy (gained from breaking down food that has been consumed or, in the case of plants, made via photosynthesis), it stores that energy by reattaching a free phosphate molecule to ADP, turning it back into ATP. The ATP molecule is just like a rechargeable battery. ... When it's run down, it's ADP.
1416578
ATP itself is a small, soluble molecule which can be easily broken down and transported around the cell. ... Finally, ATP can be deemed a good energy source as it has the ability to transfer a phosphate group, and therefore energy, to other molecules.
426488
ATP supplies energy to cells so in that sense it is like a battery. ATP is useful for energy so it is "charged" and ADP is uncharged. ... When used, it becomes ADP or Adenine Di-Phosphate. Adding another phosphate will ""recharge"" ATP.
128469
This accounts for about two ATP molecules. A total of 32 ATP molecules are generated in electron transport and oxidative phosphorylation.
139489
The ATP molecule can store energy in the form of a high energy phosphate bond joining the terminal phosphate group to the rest of the molecule. In this form, energy can be stored at one location, then moved from one part of the cell to another, where it can be released to drive other biochemical reactions.
697555
ATP is Adenosine Triphosphate and ADP is Adenosine Diphosphate. ... ADP gets converted into ATP in presence of inorganic phosphate and energy, irrespective of whether the energy is obtained from sunlight or from certain exothermic reactions. ATP is converted into ADP, releasing energy and inorganic phosphate.
790712
Within the power plants of the cell (mitochondria), energy is used to add one molecule of inorganic phosphate (P) to a molecule of adenosine diphosphate (ADP). ... The ADP and the phosphate are then free to return to the power plant and be rejoined. In this way, ATP and ADP are constantly being recycled.
1255444
ADP can be recharged back into ATP by adding a phosphate. This requires energy. These molecules can be recycled so that a constant stream of energy rich ATP is available for all metabolic pathways in the cell.

Simplified reaction: Most of the ATP produced by aerobic cellular respiration is made by oxidative phosphorylation. The energy of O2 released is used to create a chemiosmotic potential by pumping protons across a membrane. This potential is then used to drive ATP synthase and produce ATP from ADP and a phosphate group.

The total energy gained from the complete breakdown of one (six-carbon) molecule of glucose by glycolysis, the formation of 2 acetyl-CoA molecules, their catabolism in the citric acid cycle, and oxidative phosphorylation equals about 30 ATP molecules, in eukaryotes.
994144
Energy is needed at the start of glycolysis to split the glucose molecule into two pyruvate molecules. ... The energy to split glucose is provided by two molecules of ATP. As glycolysis proceeds, energy is released, and the energy is used to make four molecules of ATP.
