Unformatted text preview: KNOW HOW HOMEOSTASIS WORKS KNOW THE PHASES IN DRUG TRIALS End-Product Inhibition Occurs when 1 product in a divergent pathway inhibits activity of the branch-point enzyme Prevents final product accumulation Causes reaction to favor alternate pathway Occurs by allosteric inhibition whereby product binds to enzyme causing it to change to an inactive shape Know what Feedback inhibition is and difference between that and end product inhibition Know different mechanisms of transport- How are they different? Know the different types of bonds And where they are used You have a solution with 4 m sucrose and 1m KCl calculate the osmolality of the solution How do enzymes work? How do you define the difference structures of proteins DNA/RNA Know the differences Can you do base pairing DNA to DNA and DNA to RNA ATGCCGG TACGGCC ATGCCGG UACGGCC Gs Stimulates cAMP/Gi Inhibits cAMP Production Signal Transduction Pathway Activation of Adenylate Cyclase by Gs First messenger-glucagon GTP GTP GDP GDP s s GTP Adeylate cyclase ATP Phosphrylates Cytoplasmic targets cAMP PKA PKA cAMP Nucleus cAMP Phosphrylates Nuclear targets phosphrylation P P Activates Activates Target genes Target genes CREB GTP Cycle Activation GTP hydrolysis G G G G GDP GTP GDP GTP Exchange of GTP for GDP GDP + P Know the different ways cells communicate ...
