Energy from __________ is used to generate ATP from ADP and Pi.

a. GDP

b. ADP

c. a proton gradient

d. A Na+ gradient

e. ATP

According to the chemiosmotic theory, an electrochemical proton gradient is used to synthesize ATP in mitochondria. The enzyme that does this is located on the inside of the mitochondrial membrane. The oxidation of carbohydrates and fats is used to pump protons outside the mitochondrial membrane until the steady-state membrane potential is -140 mV and the pH gradient ∆pH = 1.5. Inside the mitochondrion, pH = 7.0, [ATP] = 1 mM, [Pi] = 2.5 mM, [ADP] = 1 mM, and T = 298 K.

a) Howw much chemical potential is required to synthesize ATP inside mitochondria? Hint: here the question refers to the chemical potential difference between products and reactants = ∆G of the reaction ADP + Pi -> ATP.

b) How much free energy is made available by moving 1 mol of protons from the outside to the inside? Is this enough to drive ATP synthesis?

c) How many protons must be translocated per ATP synthesized?

1.) Glucose 6-Phosphate + H2O -> Glucose + Pi has a Keq of270. ATP + Glucose -> ADP + Glucose 6 phosphate has a Keq of 8 90. Using this information, calculate the standard free energy ofhydrolysis of ATP.

2.)The complete combustion of glucose to CO2 and H2O proceedswith an overall ΔG° of -686 kcal/mol. When this process occurs in atypical cell, 36 mol of ATP are produced from ADP and Pi.

Assuming that the ΔG for ATP <--> ADP + Pi is -10kcal/mol, and that ΔG° = ΔG for glucose oxidation under cellularconditions, what fraction of the potential energy of glucose isconserved as chemical bond energy in ATP?

What happens to the energy not conserved as ATP bond energy?
