Question 10

What are the two types of respiration present in monera? What are it’s subtypes?

Answer 10

Aerobic (need oxygen for survival)
Divided in obligate aerobes and facultative anaerobes

Anaerobic (do not need oxygen for survival)
Divided in obligate anaerobes and facultative aerobes

What are facultative anaerobes

Answer 11

Mainly aerobe but optionally anaerobes
Eg. Mycoplasma, heterocyst of cyanobacteria

Question 12
