Energy transformation in biological systems is called
Correct answer: D. Bioenergetics
- A. Metabolism
- B. Photosynthesis
- C. Photorespiration
- D. Bioenergetics
Explanation
The correct answer is bioenergetics. Bioenergetics is dedicated to understanding how organisms acquire, transform, and utilize energy, which is essential for life processes. Metabolism refers to the broader set of chemical reactions and isn't specifically about energy transformation. Photosynthesis is a specific process of converting light energy to chemical energy, rather than a general term for energy transformation. Photorespiration is a plant-specific process that results in energy loss, not transformation.

About Bioenergetics
Cellular respiration explains how cells release energy from glucose through glycolysis, the link reaction, Krebs cycle and electron transport chain. It includes ATP production, substrate-level and oxidative phosphorylation, aerobic versus anaerobic respiration, and the roles of mitochondria, oxygen and fermentation in energy transfer.
