Which type of respiration occurs in yeast and some bacteria?

• A. Aerobic Respiration
• B. Anaerobic Respiration
• C. Photosynthesis
• D. Glycolysis

Answer: (B)

The correct answer is anaerobic respiration, which occurs in yeast and some bacteria. This process allows these organisms to convert sugars into energy without the need for oxygen. In anaerobic respiration, glucose is broken down to produce energy, and a byproduct of the process varies depending on the organism. For example, yeast typically produces ethanol and carbon dioxide during fermentation, a specific type of anaerobic respiration. This type of respiration is crucial for survival in environments where oxygen is scarce or absent, enabling yeast and some bacteria to thrive in varying conditions. Understanding anaerobic respiration highlights the metabolic flexibility of these organisms, which can switch between respiration methods based on the availability of oxygen, thereby maximizing their energy production under different environmental circumstances.
