• D. Aerobic and anaerobic respiration

Answer: (D)

Verified step by step guidance

1. Begin by understanding the concept of cellular respiration, which is the process by which cells convert nutrients into energy.
2. Identify the two main types of cellular respiration: aerobic respiration and anaerobic respiration.
3. Aerobic respiration requires oxygen to produce energy and occurs in the mitochondria of cells. It involves the complete oxidation of glucose into carbon dioxide and water, releasing energy.
4. Anaerobic respiration does not require oxygen and occurs in the cytoplasm. It involves the partial breakdown of glucose, resulting in products like lactic acid or ethanol, and releases less energy compared to aerobic respiration.
5. Recognize that both types of respiration are essential for different organisms and conditions, with aerobic respiration being more efficient in energy production.
