An allosteric enzyme with a Hill coefficient of 2.5: O a. exhibits a sigmoidal saturation profile that can shift to the left by increasing the concentration of a positive effector. O b. will be stabilized in the T-state in the presence of a negative effector....

2. Plants use the enzyme starch synthase to make starch from glucose monomers Even though starch and cellulose are both chains of glucose, plants use a different enzyme to make cellulose. If you were naming the enzyme they use to make cellulose, what would you...

An enzyme's activity is low relative to other enzymes within the same path. This enzyme: O a. likely catalyzes a reaction that has a negative AG O b. must exhibit a C value less than 0.5 c. is cooperative. O d. is the only regulator...

13. Match the hypersensitivity phenotype/pathology/mechanism with the appropriate hypersensitivity class. 4 pts A) IgG mediated, soluble antigen B) IgG mediated, tissue (non-soluble) antigen C) Pathology can take >2 days to appear D) IgE mediated Type I Type II Type IlI Type IV ...

14.You have a group of patients with apparent defects in their complement systems. Based on the scenarios described below, provide TWO potential mechanisms to explain the patient's defect. 10 pts Cell-free serum (would contain complement components, if present) is collected from each patient and added...

12. Use the diagrams to answer the following questions in reference to a DC. 10 pts A) T cell Panel B: CD? MHC-7 = T cell type - Is the antigen source of epitope B B) DC DC T cell CD? CD? TCR CD3 TCR...
