The heat produced by hydrolysis of 65 kg of ATP is -6.8 kJ.
Let's consider the thermochemical equation for the hydrolysis of ATP.
ATP + H₂O ⇒ ADP + Pi ΔG = -57 kJ/mol
We will convert 65 kg of ATP to moles using its molecular weight (507.18 g/mol).
[tex]65 \times 10^{3} g \times \frac{1mol}{507.18g} = 1.2 \times 10^{2} mol[/tex]
57 kJ of heat are released by the hydrolysis of 1 mole of ATP. The heat released by the hydrolysis of 1.2 × 10² moles of ATP is:
[tex]1.2 \times 10^{2} mol \times \frac{(-57kJ)}{1mol} = -6.8 \times 10^{3} J = -6.8 kJ[/tex]
-6.8 kJ is the heat produced by hydrolysis of 65 kg of ATP.
