Question

what is difference between internal and cellular respiration​

Answer 1

Hello!!!

Gas exchange occurs by diffusion. ... External respiration occurs in the lungs where oxygen diffuses into the blood and carbon dioxide diffuses into the alveolar air. Internal respiration occurs in the metabolizing tissues, where oxygen diffuses out of the blood and carbon dioxide diffuses out of the cells

Answer 2

Internal respiration is the processes by which gases in the air that has already been drawn into the lungs by external respiration are exchanged with gases in the blood ;that has returned to the lungs after passing through tissues around the body because carbon dioxide (CO2) is removed from the blood and replaced with oxygen (O2).The processes of internal respiration take place in the distal respiratory tree, which is described at the bottom of the page about the tracheobroncial tree.Internal respiration concerns 'gasesous exchange' 'down a gradient'. That is, gases that are at a high concentration are reduced to a lower concentration and vice-versa.

The cellular respiration is the series of metabolic processes by which living cells produce energy through the oxidation of organic substances.
