Respiration is a complete process by which oxygen is taken into the body, transported to cells and used to breakdown glucose to release energy with the production of waste products such as water and Carbon dioxide.

Respiration involves -

• Breathing
• Exchange of gases
• Cellular respiration

❍ Breathing - breathing is the first stage of respiration. It involves inhalation and exhalation.

❍ Exchange of gases - This is the second stage of respiration. this occurs in two stages in the first stage there is an exchange of Oxygen and Carbon dioxide between the inspired air inside the alveoli and the blood in the blood capillaries. This is called external respiration.

• In the second stage blood cells carry oxygen to different tissues where the exchange of gases occurs between blood cells and tissue cells this is called internal respiration.

❍ Cellular Respiration - This is the final stage of respiration. the oxygen taken up by the cells is used in breaking down food to release energy, this process is called cellular respiration.

The process can be presented by simple equation -

$\boxed{\sf{Glucose+Oxygen \longrightarrow Carbon\:dioxide+Water+Energy}}$

Cellular respiration is of two types -

• Aerobic respiration
• Anaerobic respiration

★ Aerobic Respiration - breaking down of food into carbon dioxide and water using oxygen is called aerobic respiration. Most of the living organisms such as humans animals plants show aerobic mode of respiration.

★ Anaerobic Respiration - Food can be also broken down without using oxygen this mode of respiration is called anaerobic respiration.

• Anaerobic respiration is seen in organism such as yeast and certain bacteria. They are called as anaerobes.

• Anaerobic respiration releases less energy in comparison to aerobic respiration.

• End products of anaerobic respiration differ in various organisms.

• In yeast, glucose is broken down by ethyl alcohol and carbon dioxide. The process can be explained by the simple equation -

$\boxed{\sf{Glucose \longrightarrow Ethyl\:alcohol+Carbon\:dioxide+Energy}}$
