This manuscript has been assigned Journal Series No. 03-9, College of Agricultural Sciences and natural Resources, University of Nebraska
This lesson will examine the two major classes of phototsynthetic pigments, chlorophylls and carotenoids, their biochemical structures, and their biosynthesis. The organization of these pigments into photosynthetic pigments, which are protein complexes that harvest light and convert its energy into biochemical energy, will be explained.
At the completion of this lesson, students will be able to:
- Understand the importance of conjugated double-bond systems in pigments.
- Relate the first and second excited singlet states to a pigment’s absorption spectrum.
- Understand photophosphorylation as the coupling of photochemistry to photosynthetic electron transfer.
- Describe the photosynthetic apparatus in terms of two photosystems.
- Understand that CO2 fixation relies upon the ATP and NADPH produced by photophosphorylation.
