Question

What happens in internal respiration? Where does internal respiration occur?

Answer 1

• The process by which living beings take in oxygen and use it to break down the food to release energy is called internal respiration.
• It is also called cellular respiration.
• $\mathrm{Food}+\mathrm{Oxygen}\to \mathrm{Carbon}\mathrm{dioxide}+\mathrm{Water}+\mathrm{Energy}$
• ${\mathrm{C}}_6{\mathrm{H}}_{12}{\mathrm{O}}_6\left(\mathrm{s}\right)+{\mathrm{O}}_2\left(\mathrm{g}\right)\to {\mathrm{CO}}_2\left(\mathrm{g}\right)+{\mathrm{H}}_2\mathrm{O}\left(\mathrm{l}\right)+\mathrm{Energy}$
• Internal respiration occurs in the living cells.
