What type of molecules are used to store energy in cells?

Carbohydrates
Proteins
Lipids
ATP

The correct answer is: Lipids

Lipids are the type of molecules used to store energy in cells. Lipids, also known as fats, contain twice as much energy as carbohydrates or proteins and are stored in large reserves in our bodies for long-term energy needs. While carbohydrates and proteins can also serve as sources of energy for cells, they are not the main type of molecules used for energy storage. ATP or adenosine triphosphate is a molecule that provides energy for cellular processes but is not actually stored for later use. Therefore, the other options are incorrect because they are not the main type of molecules used for storing energy in cells.
