The free energy for ATP hydrolysis in vivo is actually > the standard free energy change of -30 kJ mol-1 because ________. a. It has stronger electrostatic repulsion b. It can participate in phosphoryl group transfers c. Of the actual concentrations of ATP and its hydrolysis products in cells d. It can easily be formed from other nucleotide triphosphates

Answer :

Answer:

The correct answer will be option C.

Explanation:

ATP is the energy molecule which on hydrolysis provide energy to the cells for metabolic functions.

In vitro, the standard free energy of the ATP is -30.5 kJ/mol but its value varies in the cell as the concentration of ATP and its products like ADP, AMP and Pi are unequal in a cell. The Mg2+ in the cytosol has the ability to bind ATP and ADP, as well as the time of ATP hydrolysis, differs from cell to cell, thus influencing the concentration of ATP and its products.

Thus, option C is the correct answer.
