Question

During an endothermic process, a cell requires 4,880 kJ of energy to complete the process. How many molecules of ATP would be hydrolyzed to provide the same amount of energy?

Answer 1

Answer:

32 molecules of ATP are hydrolyzed to provide the same amount of energy

Answer 2

Given - Energy required - 4880 kJ

Find - Molecules of ATP required to provide same amount of energy.

Solution - Amount of energy released on hydrolysis lies between range of -28 to -34 kJ. The range occurs due to varying concentration of ADP and inorganic phosphate.

For the question, taking the value of energy released to be 30.5 kJ.

Thus, 30.5 kJ of energy is released by 1 ATP.

4880 kJ of energy will be released by -

(1/30.5)*4880

Amount of ATP required - 160.

Hence, 160 molecules of ATP are required.
