Why do we get instant energy from glucose?
Advertisements
उत्तर
- Glucose is the simplest type of sugar. It can be absorbed directly by the intestine and quickly carried by blood to various cells in the body, where it is oxidized with oxygen and released as carbon dioxide, water, or energy.
- In this manner, we obtain rapid energy from glucose. Carbohydrates, proteins, and so on must be broken down into simpler compounds before they can be absorbed.
- As a result, they have to spend more time producing energy.

| Bile juice is stored in a sac called, gall bladder, located near its organ of secretion, liver. The gall bladder releases the bile juice into the small intestine whenever food reaches there. Though bile juice is devoid of any digestive enzymes, it is required for the digestion of fats. The fats cannot be digested easily because they are insoluble in water and are present as large globules. Bile juice breaks down big fat droplets into smaller droplets. These are then easily digested by the enzymes released from the pancreas. |
