Conversion of light energy to chemical energy

• Chlorophylls

• Light reactions

• Photosynthesis

• None

-Carry out photosynthesis

-Most are also autotrophs that use CO2 as sole carbon source

• Photoautotrophs

• Autotrophs

• Phototrophs

• none

use energy from light to reduce CO2 to organic compounds

• Phototrophs

• Autotrophs

• Photoautotrophs

• Photoheterotrophs

-Are phototrophs that use organic carbon as a carbon source

• Photoheterotrophs

• Photoautotrophs

• Autotrophs

• none

Photoautrophy requires two sets of parallel reactions called

• Light reactions

• Dark Reaction

• Calvin Clycle

• Redox Reactions

What reaction produces ATP and NADPH?

• Light

• Dark

• Redox

• Chemical

What reaction reduce CO2 to cell material for growth

• Light

• Dark

• Calvin Cycle

• Oxidation

Photosynthesis require light sensitive pigments called_ and _ that absorb light energy.

• Chlorophylls

• Chloroplast
