Introduction:
In living cells, the concentration of ATP and the product of hydrolysis of ATP (ADP and Pi) islower than that of the standard 1 M concentrations. This is the reason why the actual free energy of ATP hydrolysis differs from the standard free energy. So, it is difficult to obtain an accurate measure of the concentrations of cellular components.
Explanation of Solution
As per the given data, the actual
Using the values, as given in the statement. The equation becomes:
The values of ATP, ADP, and Pi are given in mM. So, to covert, these values in M divide each value by 1000. The resulting values obtained would be: 0.004, 0.00135, and 0.00465 for ATP. ADP, and Pi, respectively. Here, R is the gas constant and its value is 8.134 j/mol. The temperature was given in Celsius and has been converted into kelvin for calculation. (
From the above calculation, the actual
Thus, it can be concluded that at a certain concentration of ATP, the actual value of
