Block Day- 3/7/12 Homework: -Design your own protein pathway Project- due Friday -Protein Pathways/Protein Structure QUIZ- FRI - DID YOU MISS MONDAY’S CHECKUP?-
Homework Check Circle your answer: • How does a MAO inhibitor treat depression? It decreases or increases the amount of serotonin. Circle your answer: • If the AAAD enzyme doesn’t work, will there be higher or lower amounts of serotonin?
Serotonin Homework Answers: • Less serotonin • Higher serotonin • Lower serotonin • Blocks the enzyme MAO from working which keeps serotonin available and decreases depression.

Drosophila Eye Color Pigment Network OMMOCHROME PIGMENTS PTERIDINE PIGMENTS 2-amino-4- hydroxypterdine (BLUE) Molecule A (colorless) 1 Molecule B (colorless) 3 xanthopterin (GREEN-BLUE) 2 9 4 tetrahydroiopterin ommochrome pigment (BROWN) isoxanthopterin (VIOLET-BLUE) 7 6 5 biopterin (BLUE) drosopterin (ORANGE) sepiapterin (YELLOW) 8 10 isosepiapterin (YELLOW) In order to see pigments, they must be transported into specific areas of the eye cells. All the ommochrome and pteridine pigments use the same transport proteins (labeled as protein #10 on the network) Color of fly is result of mixture of all pigments in network
