What are compounds that break down sugars and supply body energy?

• A. Carbohydrates
• B. Enzymes
• C. Proteins
• D. Lipids

Answer: (A)

Carbohydrates are the body's main source of energy. They’re made of sugar units and are digested into simple sugars like glucose. Glucose is then used in cellular respiration to generate ATP, the energy currency cells rely on. So carbohydrates are the compounds whose breakdown provides readily usable energy for the body. Enzymes, while essential, are proteins that speed up chemical reactions (including sugar breakdown) but don’t supply energy themselves. Proteins and lipids can be used for energy in certain situations, but they are not described here as the primary energy-providing compounds formed from sugar breakdown.
