The Formula for Cellular Respiration Lab
Purpose:
-To illustrate the overall equation of cellular respiration using manipulatives.
Materials:
-Sheet of paper with 18 oxygen atoms, 12 hydrogen atoms, and 6 carbon atoms
-Sheet of paper with enzyme, lightning bolt, two plus signs, and an arrow
-Scissors
-Colored Pencils/Markers
Procedures:

Cut out each individual piece and lay it out in a pile on your desk.
Using the pieces provided, construct one molecule of glucose.
Set the plus sign down after the glucose molecule.
Construct six molecules of oxygen gas. Place the oxygen molecules on the table next to the plus sign.
Lay down the arrow after the oxygen molecules to show that the materials produced as a result of
cellular respiration will be a direct result of the raw materials used as reactants.
6. Place the enzyme below the arrow to represent the materials inside of the mitochondria necessary for
cellular respiration to take place.
7. Using the reactant side of the equation, determine the pieces necessary to assemble six molecules of
carbon dioxide.
8. Move the appropriate pieces used to create six molecules of carbon dioxide to the other side of the
equation.
9. Move the plus sign over to the product side of the equation.
10. Use the remaining materials on the reactant side of the equation to form six molecules of water on the
product side of the equation.
11. Place the second plus sign after the six molecules of water.
12. Place the lightning bolt after the second plus sign to represent the ATP energy produced as a result of
cellular respiration.
13. Using the reaction you generated, complete the data and conclusion section of this lab.
