and a heterozygote (right lane) on a diagram of an agarose gel;
Answer the questions found at the following downloadable link:
Media:Taster_DTC_questions110.doc‎ to use as a template for your answers.

For help, see the Resources
section of this wiki.
3 8 Oct. 28 to
Nov. 3
Photosynthesis 1: Photosynthetic pigments Homework: Prepare a full results section
for the photosynthetic pigment identification experiment;

In your lab notebook,
prepare a flow chart for the Hill Reaction (Lab 9);
Review the mechanisms of electron transport
and proton flow in photosynthesis (use your textbook).

Nov. 10
Photosynthesis 2: Hill Reaction Homework: Finalize your self-designed experiment
testing a variable affecting the Hill Reaction;
Write a Materials and Methods style version
of the Hill Reaction experiment that you did this week in Lab 9

Nov. 17
Photosynthesis 3: Investigation of variables affecting the Hill Reaction Homework: Plot your A580 data (y-axis) versus time in seconds (x-axis)
for the different treatments
(with the treatments on the same graph).See(Appendix E).
Determine regression equations for the linear part
of each data plots to get slope (m) values
(slopes represent the rates of electron transport).
Calculate the rates (change over time of the linear portion of your graphs)
and plot those values against your variable (x-axis);

A full paper on your experiment, in the form of a scientific research report,
is due at beginning of Lab 11.

Discuss your results in terms of how the factor that you chose to investigate
affects the electron transport rate in photosynthesis.
Compare your results to other investigations published in the primary literature.
Refer to the " Guidelines for science writing"
information found in the Resources
section of the wiki.
