Which of the following is not correct about nitrogen fixation?
Carried out only by few prokaryotic organisms termed diazotrophs
It requires metabolic energy
None of the above
Enzyme that catalyzes the reduction of nitrogen is termed as nitrogenase complex
What feature of mycobacteria is responsible for the unusually slow growth of these bacteria?
They have limited numbers of ribosomes so protein production is slow.
They cannot fully metabolize carbohydrates and must rely on fermentation.
They lack a cell wall and are extremely fragile.
The mycolic acid in their cell walls requires signification metabolic investment.
Their low tolerance for oxygen retards their growth.
Which group of eubacteria complete nitrogen fixation?
proteobacteria
green bacteria
cyanobacteria
gram positive bacteria
spirochetes
chlamydia
