Announcements

• There is a quiz next week
• Group library project genetic disease
• gtpower point presentation and a written
  report
• gtwork in groups of 4
• gtthe presentation and the report should cover
  
• the following
• background information.
• molecular mechanism of the disease
• recent research on diagnosis, pathogenesis
  
• and/or treatment
• gtdue on the week of October 18th it is of 40
  points

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

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?

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
