which of the following bacterial groups lack enzymes fir carry out aerobic respiration?
a.Obligated aerobes
b. facultative aerobes
c. obligate anaerobes
d. facultative anaerobes
Answers
Answer:
Obligate anaerobes are the bacterial groups that lack enzymes to carry out aerobic respiration
Explanation:
Obligate anaerobes are unable to grow in the presence of oxygen.
They depend on fermentation and anaerobic respiration by the usage of a final electron acceptor other than oxygen.
They are found in deep soil sediments, still waters, and the bottom of the deep ocean, where there is no photosynthetic life.
Obligate aerobes require O₂ for their respiration and to oxidize substrates to obtain energy.
These aerobes possess a catalase enzyme that decomposes H₂O₂
On the contrary, anaerobic organisms do not possess these enzymes.
Facultative aerobes are not solely dependent upon the availability of O₂ for their survival.
In an aerobic environment, these organisms carry out aerobic respiration while they switch to anaerobic respiration in anaerobic conditions.
