Multiple Choice
Why do the instructions for the growth of Neisseria gonorrhoeae recommend a CO2-enriched atmosphere?
A
Neisseria gonorrhoeae is an obligate anaerobe that requires CO2 for respiration.
B
Neisseria gonorrhoeae uses CO2 as a primary energy source.
C
Neisseria gonorrhoeae is a capnophile that thrives in environments with higher levels of CO2.
D
Neisseria gonorrhoeae requires CO2 to maintain its cell wall integrity.
Verified step by step guidance

Understand the term 'capnophile': Capnophiles are microorganisms that thrive in the presence of high concentrations of carbon dioxide (CO2). They require CO2 for optimal growth, although they are not necessarily obligate anaerobes.
Identify the characteristics of Neisseria gonorrhoeae: This bacterium is known to be a capnophile, meaning it grows best in environments with elevated CO2 levels.
Consider the growth requirements: Neisseria gonorrhoeae does not use CO2 as a primary energy source nor does it require CO2 for respiration. Instead, it requires CO2 for optimal growth conditions.
Evaluate the options: The statement that Neisseria gonorrhoeae is a capnophile that thrives in environments with higher levels of CO2 aligns with its known growth requirements.
Conclude the reasoning: The recommendation for a CO2-enriched atmosphere is based on the bacterium's classification as a capnophile, which necessitates higher CO2 levels for optimal growth.
