Theodor W. Engelmann illuminated a filament of algae with light that passed through a prism, thus exposing different segments of algae to different wavelengths of light. He added aerobic bacteria and then noted in which areas the bacteria congregated. He found that the largest groups were found in the areas illuminated by the red and blue light. This experiment helped to determine the relationship between which of the following parameters?

Question 9

An early step in the process of carbon fixation combines three molecules of CO2 with three molecules of RuBP to produce three 6-carbon molecules, which are immediately converted to six 3-carbon molecules. These six molecules are phosphorylated and reduced to produce glyceraldehyde 3-phosphate (G3P). What additional events occur to complete the Calvin cycle?

On the diagram below, please draw H+ being pumped by the ETC in the photosystems, AND H+ diffusing through ATP synthase. Also indicated where O2 is utilized by writing in where and how (either typed description or chemical formula for the reaction is fine). BE CLEAR on the direction/location in which each is occurring.

Question 12

a)The experiment below is set up to measure the rate of photosynthesis. The flask are spinach chads (the gray disks) and sodim bicarbonate (the white dots). There is a light shining on the flask (you just can't see it 😄 )
Volumetric measurements are taken by reading the syringe to show the volume of gas that is changing.
In a BRIEF paragraph, answer the following questions.It could be based on a lab you viewed, or another version, as long as it uses this set-up.
a) describe the independent and dependent variables that COULD be recorded using this set up.
b) using the variables you indicated in part a, describe what would be a good positive control group.
