Presentation Transcript

  1. Photosynthesis IBDP Biology: HL/Option C

  2. Draw and label a diagram showing the structure of a chloroplast as seen in electron micrographs

  3. State that photosynthesis consists of light-dependent and light-independent reactions

  4. Complete Action vs. Absorption Spectra (- xanthophylls)

  5. Explain the light-dependent reactions

  6. e-

  7. Explain the light-dependent reactions and specifically photophosphorylation in terms of chemiosmosis

  8. Useful light dependent reaction animations:

  9. plateau CO2 is a substrate in an enyme-catalysed light-dependent reaction. At low CO2 concentration, rate is positively correlated with concentration

  10. plateau At low light intensity, rate of photosynthesis is proportional to light intensity.

  11. Optimum temperature Above the optimum temp., enzymes are denatured and rate drops steeply. Increased temp. gives increased energy and increased rate of photosynthesis Which enzymes are used in respiration?

  12. What are the conditions of each of these trials? Rate of photosynthesis Light intensity
