Breaks down food and sugars resulting in the release of energy is?

• A. Photosynthesis
• B. Respiration
• C. Transpiration
• D. Translocation

Answer: (B)

Cellular respiration is the process by which cells break down sugars to release energy. Through respiration, glucose is oxidized to produce ATP, the cell’s energy currency, with the steps of glycolysis, the Krebs cycle, and the electron transport chain in mitochondria. This energy release powers all cellular activities and metabolism, yielding ATP, water, and carbon dioxide. In contrast, photosynthesis builds sugars using light energy, transpiration is the loss of water from a plant, and translocation is the movement of sugars through the plant; none of these primarily release energy.
