Question

multiple choice question

which of the following describes a microbe that must have oxygen to survive?

obligate aerobe
facultative aerobe
passive aerobe
semi aerobe

Explanation:

Analyze the requirement for oxygen

An organism that "must have oxygen to survive" is strictly dependent on aerobic respiration for energy production and cannot grow without \(O_2\).

Define the biological terms

• Obligate aerobe: Requires oxygen for growth and survival (obligated to use oxygen).
• Facultative aerobe (or facultative anaerobe): Can grow with or without oxygen.
• Passive aerobe / Semi aerobe: Non-standard microbiological classifications for oxygen requirements.

Identify the correct term

The term "obligate" means restricted to a particular function or pathway, meaning an obligate aerobe strictly requires oxygen.

Answer:

• Obligate aerobe (Correct answer)
• Facultative aerobe
• Passive aerobe
• Semi aerobe
