Question

A large hot chocolate with whipped cream purchased at a national coffee chain contains 760 Calories. Express this quantity in terms of ATP equivalents. Recall, that the ∆G°′ for the hydrolysis of ATP is -30.5 kJ/mol. [Express your answer using 3 significant figures.]

Answer 1

Hydrolysis of ATP as follows: ATP+H,02 ADP+Pi AG=-30.5kJ/mol Convert 760 сal of hot chocolate into kJ as follows: =3.18kJ Released energy byhydrolysis of ATPis 30.5 kJ/mol. Calculate moles of ATP as follows: 3.18kJ 760calx 4.186k 760cal 10 cal 30.5kJ/mol A TP=0.104 moles ATP Calculate the ATP equivalentas follows: 0.104 moles ATP x 6.023x10^ATP equivalents 1moles ATP 6.28x10- ATP equivalents
