Organisms are highly organized, coordinated structures that consist of one or more cells. Energy is needed to perform heavy labor and exercise, but humans also use a great deal of energy while thinking and even while sleeping. Metabolism and homeostasis are examples.. Regulation of biological processes occurs when any … When these molecules are broken down during metabolism, the energy in the chemical bonds is released and can be harnessed for cellular processes. Some organisms capture energy from the sun and convert it into chemical energy in food; others use chemical energy from molecules they take in. Cells break down complex carbohydrates into simple sugars that the cell can use for energy. Some of these chemical reactions are spontaneous and release energy, whereas others require energy to proceed. Aerobic.
