Unformatted text preview: light-activates chlorophyll 3. Energy: produced when electron released by chlorophyll light 4. 6CO 2 + 12H 2 O →→→→→→→→ C 6 H 12 O 6 + 6H 2 O + 6O 2 chlorophyll → e-(glucose) 5. Phototrophs : a. Photoautotrophs - utilize inorganic compounds (i.e., CO 2 ) b. Photoheterotrophs - utilize organic compounds (i.e., methanol) B. Chemosynthesis 1. Occurs in cells that do not produce chlorophyll. 2. Energy: produced by oxidation of chemical compounds (i.e., sugars). 3. Catalyst: enzymes produced by cell. 4. Chemotrophs : a. Chemoautotrophs - utilize inorganic compounds (i.e., CO 2 ) b. Chemoheterotrophs - utilize organic compounds (i.e., glucose) 1 2...
