D:  THE LIGHT REACTION OF PHOTOSYNTHESIS

BIOCHEMISTRY - DR. JAKUBOWSKI

04/15/16

Learning Goals/Objectives for Chapter 8D: 

After class and this reading, students will be able to

  • described the mechanistic similarities between mitochondrial oxidative/phosophorylation in which NADH and FADH2 are regenerated on reduction of O2 and the light reaction of photosynthesis in which O2 and a reducing agent, NADPH are produced;
  • describe similarities in fluorescence resonance energy transfer and exciton transfer;
  • describe the difference in properties between chlorophylls acting as antennae and chlorophylls at the reaction center;
  • describe how sunlight driven excitation of chlorophyll molecules at the reaction center produces an oxidzing agent strong enough to oxide water and form O2, itself a powerful oxidizing agent;
  • explain the general flow of electrons from dioxgen to NADP+ through a series of mobile and membrane protein bound electron carriers in the Z scheme of electron transport in the chloroplast thylacoid membranes;
  • explain with picture diagrams how oxidation of H2O and phosphorylation reactions (to produce ATP) are coupled in in the Z scheme;
