Q.1) To run and play requires a strong heart. This means building cardiac muscle tissue. The machinery within a cardiac muscle fiber uses protein as building blocks for actin and myosin synthesis. These molecules are derived straight from the milk and Oreo's sucrose back in the digestive system.
2) To be able to think clearly requires healthy neurons. This means making myelin to channel the neurons along axons. The machinery within a schwann cell uses and proteins as two components for myelin synthesis. Oreos supply glucose, and fatty acids needed for myelin formation; the milk can provide the lactose also needed for myelin formation.
3) To be able to run and play requires lots of energy. The Oreo supplies both dietary fiber and glucose that are metabolically quick energy sources.
