Energy is ------- by the breakdown of complex molecules into simpler ones; such reactions are called catabolic reactions:
Correct answer: A. Released
- A. Released
- B. Consumed
- C. Produced
- D. Destroyed
Explanation
Energy is released by the breakdown of complex molecules into simpler ones, and such reactions are called catabolic reactions. Catabolic reactions involve the breakdown of larger molecules into smaller ones, and this process releases energy that can be used by the cell or organism for various metabolic activities.

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.
