Atp production in the flight muscle of the fly lucilia sericata results almost exclusively from oxidative phosphorylation. during flight, 187 ml of o2/hr·g of body weight is needed to maintain an atp concentration of 7.0 μmol/g of flight muscle. calculate the rate at which the atp pool turns over. the o2 is at 25 °c and 1.00 atm.

Use the equation PV=nRT

- P is pressure in atm

- V is volume of gas in L

- R = 0.08206 L. atm / mol. K

- T is temperature in K

Your equation should look like this:

(1atm) (0.187L) = n (0.08206) (298K)

n=0.00765 mol O2 used per hour

Then, you have to convert from mol/hr to umol/s. Divide by 3600 (one hour is equal to 3600 seconds) and multiply by 1x10^6.

Your answer should be 2.12 umol/s.
