Facultative Anaerobes:
Facultative anaerobes are a type of microorganisms that can survive and grow in both the presence and absence of oxygen. They have the ability to switch between aerobic and anaerobic metabolism depending on the availability of oxygen in their environment.
Explanation of the Correct Statement:
The correct statement regarding facultative anaerobes is option 'A': They do not require oxygen (O2) for growth but grow better in its presence.
Elaboration:
Facultative anaerobes have the metabolic flexibility to use both aerobic and anaerobic pathways to generate energy. In the absence of oxygen, they can switch to anaerobic respiration or fermentation to produce energy. However, in the presence of oxygen, they can utilize aerobic respiration, which is more efficient and yields more energy.
Benefits of Oxygen:
Although facultative anaerobes do not require oxygen for growth, they can benefit from its presence. Oxygen acts as a more efficient electron acceptor during aerobic respiration, resulting in higher energy production. Therefore, facultative anaerobes grow better in the presence of oxygen compared to anaerobic conditions.
Examples of Facultative Anaerobes:
1. Escherichia coli: This bacterium is commonly found in the intestines of humans and animals. It can grow in the presence or absence of oxygen and can switch between aerobic and anaerobic metabolism.
2. Saccharomyces cerevisiae: This yeast is used in baking and brewing. It can ferment sugars in the absence of oxygen but can also utilize oxygen for aerobic respiration if it is available.
Conclusion:
Facultative anaerobes are microorganisms that can survive and grow in both the presence and absence of oxygen. While they do not require oxygen for growth, they can utilize it for more efficient energy production. Therefore, the correct statement is that facultative anaerobes do not require oxygen for growth but grow better in its presence (option 'A').
