Question

explain the importance of glucose in our body ?​

Answer 1

$\huge \boxed {\pink{\bold{Answer}}}$

Glucose is considered the ultimate source of energy. During the metabolic activities, the glucose on oxidation yields carbon dioxide, water vapour and energy in the form of ATP. This ATP is the form of energy that can be utilised by our body. So, glucose is required by each and every cell of our body

Most of the cells in your body use glucose along with amino acids (the building blocks of protein) and fats for energy. But it's the main source of fuel for your brain. Nerve cells and chemical messengers there need it to help them process information. Without it, your brain wouldn't be able to work well.

Answer 2

Glucose is a small, simple sugar which acts as a main fuel for production of energy, especially for the brain, muscles and several other body organs and tissues.

Explanation:

Importance of glucose in our body

Brain Fuel

• The brain generally depends almost exclusively on glucose to fuel its energy needs. Due to its high energy demands and incapacity to store glucose, the brain needs a constant supply of the sugar.

Muscle Fuel

• The skeletal muscles utilize large amounts of glucose during exercise. Unlike the brain, the skeletal muscles store blood sugar in the form of glycogen, which is quickly broken down to supply glucose during physical exertion.

• Muscle tissue also normally absorbs large amounts of glucose from the bloodstream during exercise.

Fuel for Other Tissues and Organs

• The different organs and tissues of the body have the ability to use various fuels. In addition to the brain and skeletal muscles, some other important organs and tissues also depend on glucose as their main or sole fuel.

• Examples are lens and retina of the eyes, the cornea, and the red and white blood cells.

Structural Roles

• In addition to its role in energy production, the human body uses glucose with other substances to make other important structural molecules. For example, the glycoprotein collagen comprises of a protein backbone with simple sugars, including glucose.
