Why is glucose such a good energy source for cells and water is not?
-- I am thinking because water is a
bigger molecule.

glucose is a bigger by 6 times. In fact you get water our of sugar when you break in down for energy.

Water cannot contain calories or nutrients because a calorie is a unit of energy. It is actually the amount of energy required to raise the temperature of 1 gram of water to 1 degree centigrade. Therefore the caloric value of food is the amount of energy the body uses to digest that food. There is no energy required to digest water ( your body doesn't have to break down water ). A nutrient is any substance that contributes to an organism. Nutrients may be found in some spring water at a very low percentages but in bottled water, the nutrients are removed by the water purification process.

The process of digestion produces glucose, therefore it can be fed straight into body for energy. Water is needed for the process of digestion.

Glucose is C6 H12 O6. It has a lot of bonds that can be broken to give up energy easily.
Water is H2O. Not many bonds there.
