Biology
 Used by plants to generate energy
 Use energy from sun to make sugar (glucose)
 Begins at the leaf within the chloroplast
 Chlorophyll is the molecule in the chloroplast
 Radiant energy (sunlight) + 6 molecules of carbon
dioxide + 6 molecules of water
 Water enters plant through roots and travels to leaves
 Carbon dioxide and sun enter into leaf.
 1 molecule of sugar (glucose) + 6 molecules of oxygen
+ 6 molecules of water
 Glucose leaves the leaf and provides energy for the
plant.
 Light-dependent reactions require sunlight and
happen in the thylakoid
 Light-dependent reaction makes ATP and oxygen.
 Light-independent reactions do NOT require sunlight
and happen in the stroma.
 ATP with carbon dioxide is used to create glucose.
 Universal fuel for all cells
 Transports needed substances across membranes
 Activates metabolic reactions that would not occur
automatically
 Performs specific mechanical work, like moving
muscles.
 Glucose provides energy for the plant and for animals
that eat the plants.
