energy from food, while plant cells get energy from sunlight. All cells use chemical energy. is the energy stored in the bonds between atoms of every molecule. To stay alive, cells must be able to release the chemical energy in the bonds. A major energy source for most cells is stored in a sugar molecule called When you need energy, cells release chemical energy from glucose. You need food energy to run, walk, and even during sleep. Your cells use energy from food to carry out all of their activities. Think about muscle cells. When you run, muscle cells release
