Question

the digestive system breaks down the food into simple nutrients like glucose . what is the purpose of this glucose ?​

Answer 1

Required Answer:-

Our body converts complex food molecules into simple ones like Glucose. This is due to:

• Glucose is used as an source of instant energy and helps in providing energy during vigorous and heavy exercise.

• The glucose is stored in the form of Glycogen which is by the process of glycogenesis. This is reserved for times of starvation.

• Through the process of Respiration, simple sugars is oxidised to release CO2 and give out a lot of energy in the form of ATP.

The Carbohydrates are the nutrients which provide energy to our body. They are of 3 types$:$

• Monosaccharides
• Disaccharides
• Polysaccharides

The polysaccharides (starch) and disaccharides (lactose, maltose, fructose etc.) are converted to monosaccharides or simple sugars by partial digestion in buccal cavity and small intestine.

Answer 2

Answer:

Glucose is a small, simple sugar that serves as a primary fuel for energy production, especially for the brain, muscles and several other body organs and tissues.

Glucose also serves as a building block for larger structural molecules of the body, such as glycoproteins and glycolipids.
