Ch 10 photosynthesis 1. Photosynthesis converts light energy to chemical bond energy we see in food. a. An ecological perspective i. Autotrophs feed self 1. organic molecules from CO2 and sunlight 2. are producers 3. plants are photoautotroph’s ii. Heterotrophs: Live on compounds made by the other organisms. 1. dependent on photoautotroph’s 2. Required for the recycling of carbon and oxygen b. Structures of photosynthesis i. Many organism do this process, are usually chemically and morphologically similar 1. How do you think this evolved? a. Endosymbiotic process. ii. Chlorophyll- green pigment required for energy adsorption iii. Mesophyll- middle portion of leaf tissue where chlorophyll is iv. Stomata- pores that allow gas exchange in plants 1. remember the epithelium of the leaves do not allow this v. Stroma- thick fluid within the chloroplast, has low H+ concentration, not be confused with material in thylakoid space vi. Thylakoids- interconnected membranous sacks where many of the proteins that are responsible for photosynthesis reside. c. The basic equation 6 CO2 + 12H2O + light energy C6H12O6 + 6O2 +6H2O Simplified is 6 CO2 + 6H2O + light energy C6H12O6 + 6O2 Is the reverse of respiration d. photosynthesis is actually a redox reaction that results in the splitting of water i. hydrogen is extracted from water and placed on C ii. Oxygen is released iii. The process is endergonic 1. the energy boos is supplied by light e. Summary
