The first stage of aerobic respiration is ________________________

During the lecture I mentioned that the conversion of potential energy into movement using kinetic energy is not very efficient.  I gave the example of a vehicle that is powered by gasoline.  I specifically mentioned that if you put $10.00 worth of gas in your car, only a certain amount is used to move your vehicle forward. About how much of your $10.00 is lost as heat, assuming that you drive a normal gas-powered commercial sedan or light truck.

A reaction is found to have an activation energy of 38.0 kJ/mol.  If the rate constant for this reaction is 1.60 × 102 M-1s-1 at 249 K, what is the rate constant at 436 K?
