One molecule of glucose contains more than 90 times the amount of energy stored in a single molecule of ATP; however, ATP is used as an immediate source of energy by the cell.

Work Step by Step

Although glucose contains much more energy than ATP, it is not used as an immediate source of energy for the cell because it is a fast way to transfer energy. Glucose, though, is the long-term way to store energy in the cell. A cell typically only stores about a few seconds' worth of energy in the form of ATP for use immediately.
