What are the underlying concepts that this particular lesson emphasizes?
Without transforming the specifics of this lesson to the general concept, students rarely make that connection

Cellular Respiration It takes energy to
form molecular bonds
Energy is released when bonds are broken
ATP is packaged in discrete units usable by the cell

simple sugar we get in our food and is the energy source
