Describe what takes place during cellular respiration in complex organisms

Cellular respiration is the process in which an organism breaks down energy so it can be absorbed. The chemical equation is C^6H^12O^6+6O^2 ⇒ 6H^2O+6CO^2+Energy (ATP) Everything on the right side of the equation are the reactants and everything on the left are the products. This basically is saying that glucose (sugar) plus oxygen will give you carbon dioxide, water, and energy. Oh and I don't know how to type subscripts on here, so in the equation when I put ^ and a number, it was meant to be a subscript.
