What are the reactants in the equation for cellular respiration? \( \begin{array}{ll}\text { A. Oxygen and Lactic acid } & \text { C. Glucose and Oxygen } \\ \text { B. Carbon dioxide and Water } & \text { D. Water and Glucose }\end{array} \)

Cellular respiration is all about transforming energy stored in glucose into a form that our cells can actually use! The main reactants for this vital process are glucose and oxygen. Without these two essential ingredients, our cells would struggle to generate ATP, the energy currency of life. In practice, this translates into activities we all partake in, like breathing and eating! The glucose comes from the carbs we consume, while the oxygen is inhaled from the air. So next time you munch on a slice of pizza or take a deep breath, remember you're fueling your body’s powerhouse!
