The overall reaction that occurs when sugar is metabolized is

For this reaction,

(a) If 25% of the free energy change is actually converted to useful work, how many kilojoules of work are obtained when one gram of sugar is metabolized at body temperature,

(b) How many grams of sugar would a 120-lb woman have to eat to get the energy to climb the Jungfrau in the Alps, which is 4158 m high? where w = work in kilojoules, m is body mass in kilograms, and h is height in meters.)
