How is ATP created?

Answer 1

ATP can be synthesized from ADP and Pi by ATP synthase enzyme. The enzyme is powered by a proton gradient which the cell must maintain. ATP can also by synthesized by substrate level phosphorylation or substrate linked synthesis. It is made from the breaking of molecules.

Answer 2

ATP synthase (EC 3.6.3.14) is an important enzyme that provides energy for the cell to use through the synthesis of adenosine triphosphate (ATP). ATP is the most commonly used "energy currency" of cells from most organisms. It is formed from adenosine diphosphate (ADP) and inorganic phosphate (Pi), and needs energy.

The overall reaction sequence is: ADP + Pi → ATP, where ADP and Pi are joined together by ATP synthase

Energy is often released in the form of protium, or H+

, moving down an electrochemical gradient, such as from the lumen into the stroma of chloroplasts or from the inter-membrane space into the matrix in mitochondria. (Wikipedia)

Answer 3

ATP is created in the mitochondria of both plant and animal cells, as well as in chlorplasts of plants. Also, when pyruvate isn't available, the cell goes through glycolysis in the cytoplasm where 4 ATPs (2 net ATP) are formed from substrate-level phosphorylation.

Answer 4

ATP is the adenosine tri phosphate. When you say, you burn energy, it is the energy of the bond. In ATP the energy is in the tri-phosphate bond is used. Every time ATP is utilized for energy production, a phosphate group is broken down. Hence, a ATP decomes ADP. The Energies in hydrolyis of one ATP Molecule are as follows

ATP + H2O → ADP + Pi ΔG˚ = −30.5 kJ/mol (−7.3 kcal/mol)ATP + H2O → AMP + PPi ΔG˚ = −45.6 kJ/mol (−10.9 kcal/mol)

Answer 5

ATP is created when ADP and a phosphate group bind together.

Answer 6

ATP generated by oxidation fuel molecules

as in glucose, fatty acids and amino acids.

Answer 7

Glycolysis, Krebs cycle, electron transport chain
