Explanation:
1. Most of the carbohydrates in the foods you eat are digested and broken down into glucose before entering the bloodstream. Glucose in the blood is taken up into your body's cells and used to produce a fuel molecule called adenosine triphosphate (ATP) through a series of complex processes known as cellular respiration.
2. Fats are known as being a long term energy source, and the fat on your body is used a "cushioning" for your bones.
3. To break a protein down into its amino acids you will need enzymes. Enzymes are biological molecules (proteins) that act as catalysts and help complex reactions occur everywhere in life.
When the food reaches the small intestine .... it was absorbed by the villi present in it ! after absorption it reaches the blood where the food(glucose) mixes with plasma and reaches to different organ....there the food via capillaries and then via lymph reaches the cell and thus there further oxidation takes place.
so that was the path !!!
