The adenylate energy charge is an index used to measure the energy status of biological cells.. ATP or Mg-ATP is the principal molecule for storing and transferring energy in the cell : it is used for biosynthetic pathways, maintenance of transmembrane gradients, movement, cell division, etc...
These carbon molecules are oxidized into NADH and ATP. For the glucose molecule to oxidize into pyruvate, an input of ATP molecules is required. This is known as the investment phase, in which a total of two ATP molecules are consumed. At the end of glycolysis, the total yield of ATP is four molecules, but the net gain is two ATP molecules.
ATP 4− + Mg 2+ ⇌ MgATP 2−, log β 4. is particularly large. [3] The formation of the magnesium complex is a critical element in the process of ATP hydrolysis, as it weakens the link between the terminal phosphate group and the rest of the molecule. [2] [4] The energy released in ATP hydrolysis, ATP 4− + H 2 O → ADP 3− + P i −
d -Glucose + 2 [NAD] + + 2 [ADP] + 2 [P] i 2 × Pyruvate 2 × + 2 [NADH] + 2 H + + 2 [ATP] + 2 H 2 O Glycolysis pathway overview The use of symbols in this equation makes it appear unbalanced with respect to oxygen atoms, hydrogen atoms, and charges. Atom balance is maintained by the two phosphate (P i) groups: Each exists in the form of a hydrogen phosphate anion, dissociating to contribute ...
2 FADH 2 from the Krebs cycle: 2 × 1.5 ATP; Altogether this gives 4 + 3 (or 5) + 20 + 3 = 30 (or 32) ATP per molecule of glucose These figures may still require further tweaking as new structural details become available. The above value of 3 H + / ATP for the synthase assumes that the synthase translocates 9 protons, and produces 3 ATP, per ...
atp 4− + h 2 o adp 3− + hpo 2− 4 + h + Adenosine triphosphate , or ATP, acts as a free energy "currency" in all living organisms. In a spontaneous dephosphorylation reaction 30.5 kJ/mol is released, which is harnessed to drive cellular reactions.

In practice, it is closer to 14 ATP for a full oxidation cycle as 2.5 ATP per NADH molecule is produced, 1.5 ATP per each FADH 2 molecule is produced and Acetyl-CoA produces 10 ATP per rotation of the citric acid cycle [13] (according to the P/O ratio). This breakdown is as follows:
