Bacteria that thrive in oxygen are called

• A. Aerobes
• B. Anaerobes
• C. Fungi
• D. Pathogens

Answer: (A)

Organisms that require or thrive in the presence of oxygen are called aerobes. They rely on oxygen for energy production through aerobic respiration in the electron transport chain, which yields more energy than anaerobic processes. This reliance is supported by enzymes that detoxify reactive oxygen species, such as catalase and superoxide dismutase, enabling them to grow well in oxygen-rich environments. In contrast, anaerobes do not require oxygen and may even be harmed by it. Fungi are a separate group of organisms not defined by their oxygen needs, and pathogens are disease-causing organisms, a label that doesn’t specify whether they prefer or tolerate oxygen.
