Week of October 15, 2012
          The process of changing light energy to chemical energy
          Energy stored as sugar
          Occurs in plants and some algae
          Plants need light energy, CO2, and H2O
          Takes place in the chloroplasts, using chlorophyll, the green pigment in plants.
                               6CO2 + 6H2O + Light Energy ------>C6H12O6 + 6O2                 carbon dioxide + water + sun's light --------> glucose + oxygen 
   Cellular Respiration

         The breakdown of glucose molecules (from photosynthesis in plants) to release energy
         Takes place in all living things in the mitochondria of the cell.
         Respiration is the opposite of photosynthesis. 
                    C6H12O+  6O2 ----------> 6CO2+6H2O
                     glucose + oxygen ------>  carbon dioxide + water            

Oxygen combines with sugars to break molecular bonds, releasing the energy (in the form of ATP) contained in those bonds. In addition to the energy released, the products of the reaction are carbon dioxide and water.

The Respiratory System
       Purpose of the respiratory system (exchange of gases)
          To provide a constant supply of oxygen to keep your body cells functioning.
          To remove carbon dioxide from the body cells.
