Explain how food provides us with energy and the substances needed to live.
(provide details about photosynthesis, respiration, ATP, carbohydrates (glucose), minerals, amino acids, lipids and vitamins)
When we eat and drink, our bodies break food down into molecules of nutrients. The nutrients travel to our stomachs, where they interact and are broken down further by digestive juices containing enzymes. The molecules are then absorbed into our blood stream after carbohydrates are also broken down. Carbohydrates are broken down to form the simple sugar of glucose. Mitochondria in our cells use energy from food to attach a third phosphate group to a molecule, forming ATP, the type of energy our body functions with. The molecules, except for fat because it gets stored, are then absorbed into our blood stream and carried to our organs. Vitamins absorb in our livers and in the fatty parts of our bodies and are essential in the process of converting carbohydrates to sugars.
