,Key Concepts
• Photosynthesis converts light energy to the chemical
energy of food in a series of steps
– The light reactions convert solar energy to the chemical
energy of ATP and NADPH
– The Calvin cycle uses the chemical energy of ATP and
NADPH to reduce CO2 to sugar
,Overview: The Process That Feeds the
Biosphere
• Photosynthesis converts solar energy into chemical
energy
• Directly or indirectly, photosynthesis nourishes almost the
entire living world

Review
• Autotrophs are producers, producing organic molecules
from CO2 and other inorganic molecules.
• Almost all plants are photoautotrophs, which means they
use the energy from sunlight to make organic molecules.
