Question

Which statement regarding ATP is false? Compared with other phosphate‑containing compounds in biochemistry, ATP has a higher free energy than nearly all of the others. Most enzymes that use ATP bind it in a form complexed with Mg2+. ATP concentrations in a cell are usually much higher than the equilibrium concentration for ATP hydrolysis. ATP can act as a group donor in adenylylation reactions.

Answer 1

Answer:

The correct answer will be option- ATP concentrations in a cell are usually much higher than the equilibrium concentration for ATP hydrolysis

Explanation:

Adenosine Triphosphate or ATP is known as the energy currency of the cell as it provides energy during the metabolic reactions.

The study on the structure of ATP revealed that it contains ribose sugar attached with three phosphates group bonded to each other via two phosphoanhydride bonds.

The metabolic reaction usually uses Magnesium bonded ATP as Magnesium covers the negative charge of the triphosphate which allows the ATP to bind hydrophobic clefts of the active site.

The ATP also transfers the adenyl group to the nucleophile which helps generate the pyrophosphate.
