Write "Respiration Notes" and then all of the following in your journal.

Respiration is:

Breaking down food to release energy or grow.
Enzymes in cells help sugar (C6H12O6) and oxygen (O2) react to release energy, carbon dioxide (CO2) and water (H2O).

Other Details:

Matter is conserved (the same number and type of atoms are present on both sides of the formula).
All organisms need to do respiration to live.
