🔋 Your Body's Power Station

Imagine your body as a city that never sleeps. Every cell is a building that needs electricity — for lights, heating, machinery, and communication. Where does all that power come from? Respiration is your body's power station: it takes glucose (the fuel) and converts it into ATP (the electricity) that every cell needs to function. Just like a real power station burns fuel to generate electricity, your cells "burn" glucose to release energy — and just like a power station, they produce waste gases (CO₂) and heat in the process.

Quick Recall Flashcards

Word equation for aerobic respiration?
glucose + oxygen → carbon dioxide + water (+ energy released)
Is respiration endothermic or exothermic?
Exothermic — it releases energy from glucose. This energy is used for movement, growth, and keeping warm.
