Which type of cellular respiration requires oxygen?

• A. Fermentation
• B. Photosynthesis
• C. Aerobic respiration
• D. Anaerobic respiration

Answer: (C)

Verified step by step guidance

1. Step 1: Understand the concept of cellular respiration. Cellular respiration is the process by which cells convert glucose into energy (ATP). It can occur in the presence or absence of oxygen.
2. Step 2: Learn the difference between aerobic and anaerobic respiration. Aerobic respiration requires oxygen to produce ATP, while anaerobic respiration does not use oxygen and typically produces less ATP.
3. Step 3: Recognize that fermentation is a type of anaerobic respiration. It occurs in the absence of oxygen and results in byproducts like lactic acid or ethanol, depending on the organism.
4. Step 4: Understand that photosynthesis is not a form of cellular respiration. It is the process by which plants and some other organisms convert light energy into chemical energy stored in glucose.
5. Step 5: Conclude that aerobic respiration is the type of cellular respiration that requires oxygen, as it uses oxygen to break down glucose completely into carbon dioxide and water, producing a high yield of ATP.
