Much of our energy requirement is provided by the breakdown of carbohydrates, found in food such as bread and potatoes into sugars.
The most common sugars obtained from food are glucose, fructose and galactose.
These are first transported to the Liver, where fructose and galactose are converted into glucose.
Cells obtain energy from glucose by breaking it down into a substance called pyruvic acid.
The energy released by this process is temporarily stored as a high energy compound, adensine- tri- phosphate.
Hence the importance of eating a healthy balanced diet.
