|
Photosynthesis
|
the process by which light energy is converted to chemical energy
|
|
|
Autotrophs
|
organisms that use energy from sunlight or inorganic substances to make organic compounds
|
|
|
Heterotrophs
|
organisms that must get energy from food instead of directly from sunlight or inorganic substances. Get energy from food through cellular respiration.
|
|
|
Cellular Respiration
|
releases the energy in food to make ATP
|
|
|
ATP
|
delivers energy to cells that they need to carry out activities
|
|
|
NADPH
|
energy carrier molecule
|
|
|
Pigments
|
light-absorbing substances that absorb certain wavelengths and reflect all the others. Located in chloroplasts
|
|
|
Chlorophyll
|
primary pigment involved in photosynthesis, reflects green light
|
|
|
Cartenoids
|
absorb different wavelengths of light than chlorophyll
|
|
|
Thylakoids
|
disk-shaped structures
|
|
|
H+
|
hydrogen ions which are left when chlorophyll molecules take the electrons from hydrogen atoms which are eventually pumped into the thylakoid and then exit
|
|
|
Electron transport chains
|
a series of molecules that electrons pass through on the thylakoid membrane
|
|
|
Carbon Dioxide Fixation
|
the transfer of carbon dioxide to organic compounds
|
|
|
Calvin Cycle
|
a series of enzyme-assisted chemical reactions that produces a three-carbon sugar
