1. Photosynthesis II

2. Announcements There is a quiz next week -Group library project “genetic disease” >power point presentation and a written report >work in groups of 4 >the presentation and the report should cover the following :background information. :molecular mechanism of the disease :recent research on diagnosis, pathogenesis and/or treatment >due on the week of October 18 th & it is of 40 points

3. Photosynthesis Experiment of the last week -the bicarbonate buffer worked as positive control -the colored buffers photosynthesis work well at wave length 400-450nm and 650-700nm -Diuron work at very early step of the reaction (photosystemII) and it block release of oxygen. While DBMIB work in a step later than DCPIP and it does not block the release of oxygen. -DCPIP, the reaction will continue b/c it work in a step latter than photosystem I

4. Today -we will perfrom the photosynthesis on a molecular level with DCPIP as electron acceptor (Hill reaction) -the hyposythesis (question) “is the rate of Hill reaction (photosynthesis) is dependant on intensity of light?”

5. Lab. report -it worth 40 points -It is group lab report -It has to be formal. There is an example lab. report that you can use it as a guide and it is posted on the server. abstract 10 introduction 7 material and methods 5 results 8 discussion 10
