I WONDER - What Is Chemical Energy?

Chemical energy is stored in the bonds between atoms and molecules. A chocolate chip cookie serves as an example of an energy storage unit, containing sugars, fats, and proteins with chemical bonds. When consumed, the body's digestive and metabolic processes break these bonds to release energy, which is then used to power physical activities and brain functions.

What type of energy is stored in the bonds between atoms and molecules?

• Nuclear energy

What happens to the chemical bonds in food during digestion?

• They are stored for later use

• They are converted into water

• They are broken to release energy

• They are strengthened

What does the released energy from food fuel in the body?
