1. Mitochondria are often called the "powerhouse of the cell" because they produce ATP, the main energy currency used by cells for various functions.
2. Glucose is broken down in the mitochondria during cellular respiration, specifically in the Krebs cycle and electron transport chain, to release energy stored in its chemical bonds.
3. Fats (lipids) yield more energy per gram than carbohydrates or proteins, making them the most energy-dense macronutrient.
4. In humans and other animals, glucose comes from the digestion of dietary carbohydrates, which are broken down into simple sugars like glucose that enter the bloodstream.
5. The process is called cellular respiration, which converts the chemical energy in food molecules (like glucose) into ATP through a series of metabolic reactions.
6. C₆H₁₂O₆ + 6O₂ → 6CO₂ + 6H₂O + ATP
- Reactants: Glucose (C₆H₁₂O₆) and Oxygen (O₂)
- Products: Carbon Dioxide (CO₂), Water (H₂O), and ATP
