5. Consider the complete oxidation of ethanol to CO2 in the liver. Ethanol is first converted to acetyl CoA by the following pathway (note that the activation of acetic acid to acetyl CoA is similar to the energy required for fatty acid activation): AMP ATP +PP NAD- NADH H S-COA NAD NADH +H CoASH H,O a) (5 points) If all electron carriers produced by the complete oxidation of ethanol to CO2 are oxidized by the electron transport chain, how many protons would be pumped from the matrix to intermembrane space? b) (4 points) How much energy would be stored per mole of ethanol as a chemiosmotic gradient due to the protons pumped at 37°C (assume that the pH is 0.4 units lower on the outside than on the inside and that there is a membrane potential of 210 mV that is positive on the outside)? c) (2 points) Based solely on the energy calculated above and the AG of -50 kJ/mole for the hydrolysis of ATP, how many moles of ATP could be produced from a mole of ethanol via oxidative phosphorylation?
