PHOTOSYNTHESIS I

Learn about the process of photosynthesis, including the role of chloroplasts, thylakoids, and the stroma. Understand how sunlight, carbon dioxide, and water are converted into oxygen and carbohydrates. Explore the two parts of photosynthesis: light reactions, which produce ATP and NADPH, and the Calvin Cycle, which uses ATP and NADPH to synthesize carbohydrates. Discover how energy is made through ATP and NADPH formation.

Presentation Transcript

  1. PHOTOSYNTHESIS I

  2. Chloroplasts • Chloroplasts contain thylakoids • Granum is stack of thylakoids • Stroma is the solution surrounding the grana

  3. PHOTOSYNTHESIS OVERVIEW sunlight 6CO2 + 6 H2O ---> 6O2 + C6H12O6 sunlight carbon dioxide + water ---> oxygen + carbohydrates

  4. PHOTOSYNTHESIS OCCURS IN TWO PARTS LIGHT REACTIONS: Make energy in the form of ATP and NADPH CALVIN CYCLE: Uses the ATP and NADPH to make carbohydrates

  5. Making Energy ATP • Build up of H+ on one side • H+ move from high to low CONC and pass through ATP synthase ADP + Pi  ATP

  6. Making Energy Cont. NADPH NADP+ + H+  NADPH
