3 PHOTOSYNTHESIS What does a plant need to survive? _________________ Which of the above is organic?____________
4 PHOTOSYNTHESISPhotosynthesis is the process by which plants convert inorganic molecules into organic molecules.Photosynthesis is the process by which plants convert light energy into chemical bond energy.Photosynthesis is the process by which plants convert sunlight into glucose.
5 PHOTOSYNTHESISChloroplasts are the site of photosynthesis
6 PHOTOSYNTHESISElectron Micrograph of a chloroplast
13 Dark Phase/ReactionIn order for the DARK PHASE to occur, HYDROGEN has to be carried from the LIGHT PHASE to the DARK PHASE.This carrier molecule is called NADP.When NADP is carrying hydrogen, it is NADPH.
14 Dark Phase/Reaction Also called Light Independent Reaction Also called Carbon Fixation.In this phase, CARBON DIOXIDE from the atmosphere combines with HYDROGEN from the light reaction to form GLUCOSE.ATP is diffused from the grana into the stroma for the dark reaction.
15 Carbon Fixation Formula and drawing of Dark Reaction: CO2 + H2 2 PGAL glucose
16 Factors Effecting Photosynthesis TemperatureLight IntensityAvailability of WaterElevation
23 ANAEROBIC RESPIRATION Occurs in the CYTOPLASMMakes energy WITHOUT using oxygen.Glucose is partially broken down.Also called GLYCOLYSIS or FERMENTATION.Produces:Ethyl Alcohol ( in yeast)Lactic Acid (in bacteria or human muscle cells).
24 ANAEROBIC RESPIRATION Pyruvic Acidproduced by the breakdown of sugars during GLYCOLOSIS
