Solution

The two primary sources of fuel for cells are Carbohydrates and Fats.

Here's why:

  1. Carbohydrates: These are the body's main source of energy. When you consume carbohydrates, your body breaks them down into sugars, which are absorbed into the bloodstream. As the sugar level rises in your body, the pancreas releases a hormone called insulin, which is needed to move sugar from the blood into the cells, where the sugar can be used as a source of energy.

  2. Fats: These are a secondary source of energy. When the body has used up the energy from carbohydrates, it begins to break down the fats. Fats are broken down into fatty acids and glycerol, which can be used to make energy.

Water and proteins are not primary sources of energy. Water is vital for many bodily functions, including regulating body temperature and transporting nutrients. Proteins are primarily used for building and repairing tissues, not for energy.
