What are two types of anaerobic respiration?
Anaerobic respiration is the production of energy without the presence of oxygen and it occurs in some yeast and bacteria, and in muscle tissue during strenuous exercise when there is insufficient oxygen. Fermentation is a type of anaerobic pathway used by certain species of bacteria that live in anaerobic environments such as stagnant ponds or decaying vegetation. Other types of anaerobic pathways are carried out by certain species of archaebacteria that live in extreme environments, such as hypothermal vents, springs of hot water in the deep ocean.
