1.	Question : What is included in components of food ? What is their contribution in metabolic processes ?
Answer» Solution :Food is the basic requirement of all living organisms. The major components of our food are carbohydrates, proteins and fats. Minerals are also required in small quantities. Food provides energy. Food also provides organic materials for growth and repair of tissues. The water we TAKE in plays part in metabolic processes. It prevents dehydration of the body. Bio-macromolecules in food cannot be UTILISED by our body in their ORIGINAL form. They have to be broken down and converted into simple substances in the digestive system. The process of conversion of complex food substances into simple absorbable FORMS is called digestion and is carried out by our digestive system by MECHANICAL and biochemical methods.
