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.
