Question

I am stuck on Part C. The answer is NOT 2.70, 1.89, or 14.11 mM!

Part A H transport from the outside of the IMM into the matrix drives this process. The pH inside the matrix is 8.2, and the outside is more acidic by 0.8 pH units. Assuming the IMM membrane potential is 168 mV (inside negative calculate ?G for the transport of 1 mol of H + across the IMI d into the matrix at 37 C 1 HI nsid ) Express your answer to three significant figures and include the appropriate units. (outside) Previous Answers Correct

Explanation / Answer

Free energy=membrane potential +RTln (k)

-11700=-.168+((8.314*36*ln (ADP)(Pi)/(ATP)

-11700=-.168+(307.62*(ln ADP +ln 5.2 -ln 2.7)

ln ADP is the unknown now. Find it.
