light-dependent reactions
produce oxygen gas and convert ADP and NADP into energy carriers NADPH
calvin cycle
uses ATP and NADPH from the light-dependent reactions energy sugars
the sun
Where does the energy in most food oringinally come from?
autotrophs
What are organisms that obtain energy from the food they eat called?
adenosine triphosphate
principal chemical compound that cell uses to store energy
photosynthesis
plants use the energy of sunlight to convert water and carbon dioxide into oxygen and high-energy carbohydrates
6CO(2)+6H(2)O=C(6)H(12)O(6)+6O(2)
photosenthesis equation

the blue and red regions
