Which bioenergetic reaction converts food in to a usable form of energy, ATP? Which bioenergetic reaction converts the sun’s energy into a chemical form of energy, glucose? Where does this reaction happen?
When you digest food, your body transfers small packets of energy from the food that you ate to a biological molecule called Adenosine Triphosphate (ATP). ATP
After all of the energy is squeezed out of the food that you ate and transferred to ATP molecules, the dead matter is excreted.

ATP is found in every cell of your body. Every cell in your body uses ATP to do work. ATP is cellular energy. Your body is entirely powered by ATP
Write “Adenosine Triphosphate” 1. On your paper 2. On your neighbor’s paper
Watch as Ms. Kuipers demonstrates the process of converting (changing) energy from food into a form that cells can use. In the space below, record what happens during her demonstration. (What important steps do you think you are observing?)
Energy is stored in between the phosphate bonds.
When a phosphate is broken off of ATP, energy is released. This is kinetic energy that can be used to do work.
Energy is stored in the new phosphate bond. This is potential energy that is stored.
1. Cellular respiration makes ATP by joining phosphate groups to ADP to make the ATP 2. The cell uses the ATP to do work. As part of this process the chemical bond between the 3rd phosphate group in the ATP is broken and energy is transfered to other molecules of the cell and lost as heat. 3. ADP and phosphate produced by the breakdown are now recycled into cellular respiration.
Which of the following correctly describes how organisms use the ADP molecule? a) Organisms release energy for use by removing one phosphate group from the molecule. b) Organisms break down maltose into a simpler sugar for use in protein-building. c) Organisms absorb energy by adding one phosphate group to the molecule. d) Organisms convert ADP into sugar to provide the organisms with a more usable form of energy.
