Question

define respiration. ​

Answer 1

It is a biochemical process in which the cells of an organism obtain energy by combining oxygen and glucose resulting in the release of CO2,H2O and ATP

Answer 2

$\textbf{\large{\underline{\underline{Respiration :}}}}$

• Respiration is a complete process by which oxygen is taken into the body , transported to the cell and used to break down glucose to release energy with the production of waste products such as water and carbon dioxide.

In other words :

The process of taking air in , exchanging the much needed gases with waste gases and then using the needed gases.

There are 2 types of respiration :

★ $\textbf{\large{\underline{\underline{Aerobic Respiration}}}}$

★ $\textbf{\large{\underline{\underline{Anaerobic Respiration}}}}$

$\textbf{\small{\underline{Aerobic Respiration}}}$

• The breaking down of food (Glucose) into carbon dioxide and water using oxygen is aerobic respiration.

• Most living organism such as humans, animals , plants and fungi show aerobic mode of respiration.

The process of Anaerobic Respiration :

Glucose + Oxygen ———⟩⟩ Carbon dioxide + Water + Energy. 

$\textbf{\small{\underline{Anaerobic Respiration }}}$

• The breaking down of food without the usage of oxygen is Anaerobic Respiration.

• Anaerobic respiration is seen in organisms such as yeast and certain bacteria.

• Anaerobic respiration release less energy in comparison to Aerobic respiration.

The process of Anaerobic Respiration :

Glucose ———⟩⟩ Ethyl alcohol + Carbon dioxide + Energy
