Set 24 – Lab 10: Photosynthesis Here is a graph of the absorption spectrum of the pigments extracted from the basil leaves: Based on this graph, which colors is most likely to pass through the basil leaf pigments without being absorbed? 

Set 11 – Lab 7: Enzymes Part 1: What substances did you use to test for the optimum pH activity? (3 pts.) Part 2: What other substances around the house do you think you could use as an alternate acid and a base to test for optimum pH? (2 pts.)  

Glutamine synthetase catalysis requires transient _________ of the gamma-carboxyl group of glutamate.

The root “dox” (a) means?  

The root “dys” means abnormal. Write one word that contains the root “dys” meaning abnormal. 

The root “christos” means?

To acidify the lumen of lysosomes (compartments in the cell involved in breakdown and recycling of biomolecules), V-type ATPase transporters are used to pump protons (H+) into the lumen (interior) of the lysosome. If the pH of the inside of the cell (cytosol) is 7.4 (4 x 10-8 M H+) and the luminal pH of the lysosome is 4.0 (1 x 10-4 M H+), calculate the free energy for a mole of protons (H+) to be pumped from the cytosol into the lumen of the lysosome. Note: We can consider, when determining membrane potential, that the movement of a solute molecule from the cytosol into the lumen of a lysosome is the same as movement from the inside of the cell to outside the cell. Assume: ΔGt = RT ln(C2/C1) or ΔGt = RT ln(C2/C1) + Z FΔψ T= 310 K R= 8.315 J/mol*K F= 96,480 J/mol*V (Faraday’s constant) Δψ = −50 mV (membrane potential, inside)
