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.
