What is the main difference between aerobic respiration and anaerobic respiration?
garri49 [273]
The main difference between aerobic respiration and anaerobic respiration is that aerobic using oxygen in the reaction, while anaerobic does not.

Even though both aerobic and anaerobic respiration releases energy, but their reactants and other products are completely different.
For example in human, in aerobic respiration, oxygen and glucose reacts to give out carbon dioxide and water; while in anaerobic respiration, which usually happens during exercise when oxygen is not enough, the muscle cells uses only glucose to produce energy and lactic acid.

Therefore, the main difference is where aerobic uses oxygen, and anaerobic don’t.

Due to environmental changes, the water concentration outside of a cell becomes lower than the water concentration inside of the
Luden [163]
Since the water concentration (also the water potential) is lower than the cell inside, the water will most likely flow from the cell out to the outside. This is because of osmosis, where the rule is water molecules will flow from a region of higher water potential to a region of lower water potential, through a semi permeable membrane (cell membrane).

When the cell looses water, depending its whether a animal or plant cell, if it's an animal cell, it'll shrink. If it's an plant cell, since there is the presence of the cell wall, the cell membrane will detach from the cell wall, and this phenomenon is called plasmolysis.
