1. how much ATP does a person possess in their body?
a. 30 trillion cells / person
b. 1 billion ATP / cell
c. 507.18g/mol ATP

Therefore,
d. 30trillion * 1billion = 30 billion trillion ATP / person or 0.0498mol ATP / person
e. given c this is equivalent to 25.266g ATP / person

2. how much ATP is consumed by a person?
f. 1 billion ATP / cell / min
g. [1 billion ATP / cell / min] / [1 billion ATP / cell] = 1 min (ie on average every cell burns its entire reservoir of ATP in a single minute)
