1. Cellular respiration releases energy by breaking down \( \begin{array}{ll}\text { A. Glucose } & \text { D. Watbon dioxide } \\ \text { B. Oxygen } & \end{array} \)

Cellular respiration is like throwing a mini-party in your cells, where glucose is the star of the show! When glucose is broken down in the presence of oxygen, it releases energy in the form of ATP, the energy currency that powers all cellular processes. So, think of glucose as the delightful cake that fuels the energy festivities! In practical terms, cellular respiration is vital for life. From the tiny bacteria in deep ocean vents to the towering redwoods in a forest, organisms rely on this process to produce energy. For humans, this means everything from jogging in the park to running those dreaded errands requires cellular respiration to keep our energy levels up!
