Question

What are the differences between aerobic and anaerobic respiration? Name some organisms that use the anaerobic mode of respiration.

Answer 1

	Aerobic respiration		Anaerobic respiration
1	It occurs in the presence of O2	1	It occurs in the absence of O2
2	It involves the exchange of gases between the organism and the outside environment	2	The exchange of gases is absent
3	It occurs in cytoplasm and mitochondria	3	It occurs only in the cytoplasm
4	It always releases CO2 and H2O	4	End products vary.
5	It yields 36 ATPs.	5	It yields only 2 ATPs.

Anaerobic respiration occurs in the roots of some waterlogged plants, some parasitic worms,animal muscles, and some micro-organisms such as yeasts.
