Photosynthesis

• Photosynthesis is a process by which sunlight energy is used to power the production of glucose and oxygen from carbon dioxide and water
• Photosynthesis chemical equation: 6CO2+12H2O-->C6H12O6+6O2+6H2O
• Light-dependent reactions occur in thylakoid membranes, where light energy is absorbed by chlorophyll pigments and converted into ATP and NADPH.
• Thylakoids are flattened sacs within chloroplasts where light-dependent reactions take place.
• Tiny pores on the surface of the leaves known as the stomata, open to allow carbon dioxide in the atmosphere to diffuse into the leaf.
• The purpose of the light dependent stage is to generate high energy co enzymes NADPH and ATP to power the second stage of photosynthesis.
• Light dependent stage inputs: 12 H2O, 12 NADP+, 18 ADP + Pi
• Light dependent stage outputs: 6O2, 12NADPH, 18 ATP
• Light independent stage inputs: 6CO2, 12NADPH, 18 ATP
• Light independent stage outputs: glucose, 6 H2O, 12 NADP+, 18 ADP+Pi
