Did the glucose turn into energy to move the muscle cell? What is your evidence? In your body, there is actually a step between the chemical energy in glucose being transferred to useful kinetic energy in a muscle cell. Instead, your body first uses the chemical energy in glucose to build a molecule called ATP (Adenosine triphosphate) out of ADP (Adenosine diphosphate) and P. When the last P is removed from ADP, the chemical energy in ATP that is released is what is used as energy. “useful” Fill out the following energy diagram showing the transfer of stored chemical energy in glucose to useful kinetic energy in a muscle cell: As the useful kinetic energy is used in a process such as a muscle contraction, that kinetic energy is transferred into the surrounding tissues as thermal energy. This is why you get warmer when you exercise. That thermal energy is then transferred to the environment. Draw the energy diagram showing the transfer of stored chemical energy in glucose all the way into the environment as thermal energy: PUTTING IT ALL TOGETHER: ENERGY IN CELLULAR RESPIRATION How much energy was immediately released to the environment as thermal energy? ______% How much energy was transformed into useful energy? ______% Where was the energy stored to begin with? Where does all the energy ultimately end up?
