The purpose of the digestive system is to break down food into simple molecules that the cells of the body can use.
Food is broken down into its simplest units called monomers. Proteins are broken down into amino acids, fats are broken down into fatty acids and glycerol while carbohydrates are broken down into glucose units.
Glucose is taken in by the cells of the body and through the process of cellular respiration is used to produce the ATP, the form of energy that cells use. Cellular respiration is the process by which cells use glucose to produce energy to power their functions.

Nucleus - control center</h2>
The nucleus is called the control center of the cell because:
- The genetic material which is the essence of life is hosted in the nucleus – the DNA-which presents the code of life or information or instructions regarding:
- The structure and function of each cell and the organ it is present,
- Numerous activities of life like reproduction, metabolism, growth, development, etc.
- The nucleus replicates the genetic information and passes to the new daughter cells, generation after generation to continue the life processes.
- The nucleus DNA transcribes the code or information for protein synthesis to the RNA to synthesize proteins in the body which carry out many essential functions in the form of structural proteins, antibodies, hormones, pigments, etc.
- The nucleus DNA synthesizes enzymes which carry out functions like metabolism.
