Chemistry/hydrolysis of ATP

posted by .

Cells use the hydrolysis of ATP as a source of energy. The conversion of ATP to ADP has a standard free energy change of -30.5 kJ/mol. If all the free energy from the metabolism of glucose.
C6H12O6(s)+6O2(g)¨6CO2(g)+6H2O(l)
goes into the conversion of ADP to ATP, how many moles of ATP can be produced for each mole of glucose?

    A freshman studying medicine at an Ivy League College is a part of his class crew team and exercises regularly. After a particularly strenuous exercise session, he experiences severe cramps in his thighs and pain in his biceps.

    Explain the chemical process that occurred in his muscle cells to cause this discomfort.


    Explain the chemical reactions that have possibly taken place in his body after the exercise.


    Discuss possible treatments for the freshman and how the treatment works chemically.
