Why to drink water if it is produced during the chemical reactions during respiration?

Why to drink water if it is produced during the chemical reactions during respiration?

The formula for respiration is:

Glucose + Oxygen –> water + Carbon dioxide + Energy (ATP)

Asked a group of students of class VII, KV AFS Bidar

Answer:

Water is just a product during respiration. The amount of water obtained during respiration is not sufficient to carry out all the functions. Water has a multitude of functions in human body. See the picture below.

FUNCTIONS OF WATER IN HUMAN BODY
FUNCTIONS OF WATER IN HUMAN BODY

About 78% of human body is water.

The water:

  • Transports nutrients and oxygen into cells
  • Moisturizes the air in lungs
  • Helps with metabolism
  • Protects our vital organ
  • Helps our organs to absorb nutrients better
  • Regulates body temperature
  • Detoxifies
  • Protects and moisturizes our joints

For all the above functions we require more water than produced as a byproduct of respiration.
