If its a major class and theyre still sucking that bad at it, its their own problem. Should have picked a different major.

1) Define catalyst? (1)










2) Describe (in depth) the enzyme-substrate complex starting from step 1? And what are 3 different ways a substrate can bind to an active site of an enzyme? (3)


















3) What are cofactors and what happens to an enzyme when one binds to its active site? (2)








4) What is Allosteric modulation? (2)









5) What is plasmolysis? (1)
A) The expansion of the cytoplasm of a plant cell in response to diffusion of water inside of the cell from a hypotonic solution (low salt concentration) surrounding the cell.
B) The shrinking of a plant cell in response to diffusion of water inside of the cell from a hypotonic solution (low salt concentration) surrounding the cell
C) The shrinking of the cytoplasm of a plant cell in response to diffusion of water out of the cell and into a hypertonic solution (high salt concentration) surrounding the cell.
D) None of the Above

6) As a young scientist you design a project to see if northern pike (Esox lucious) are selective predators. So you research the feeding habits of adult northern pike. At the reservoir that you have selected to study, the prey availability for adult northern pike is 15% Smallmouth bass (Micropterus dolomieu), 10% catfish (Ictaluridae), 20% minnows (Cyprinidae), 23% walleye (Stizostedion vitreum), and 32% redbreast sunfish (Lepomis auritus). You sample your reservoir with various passive sampling techniques and come up with 84 adult northern pike. After completing a stomach content analysis you find 16 smallmouth bass, 12 catfish, 14 minnows, 11 walleye, and 31 redbreast sunfish. State your Null and Alternative hypothesis and perform the chi-square goodness of fit test using the .05 alpha level. Show your work! (5)
