Question

Why do we get instant energy from glucose?

Answer in Brief

Solution

  • 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.
