Final answer:
Cells can be compared to a sugar factory because they have the ability to store and convert sugar molecules into usable energy. The energy stored in the sugar molecules is released through chemical reactions and used to produce ATP molecules. Carbohydrates synthesized from glucose act as the cell's savings accounts.
Step-by-step explanation:
Cells can be compared to a sugar factory because they have the ability to store and convert sugar molecules into usable energy. When cells need energy to perform work, the sugar molecules are broken down through chemical reactions, releasing the stored energy. This energy is used to produce ATP molecules, which act as the cell's energy currency. Carbohydrates synthesized from glucose can be thought of as the cell's savings accounts.
