12982038109Compare and contrast an MM Enzyme Kinetics plot & the Lineweaver-Burke PlotsIntercepts?1
12982055817what is Km and how can it be used to measure an enzyme's affinity for it's substrate?the concentration of [S] where half the enzyme is filled & a low Km= high affinity and a high Km= low affinity2
12982105249How does competitive inhibition affect Km & Vmax? What does the Lineweaver-Burke Plot look like?Increases Km, Vmax stays the same b/c if we flood a bunch of substrate, can overcome competitors; Lineweaver Burke plot becomes steeper and x-intercept moves toward center3
12982129411How does a noncompetitor affect Km & vmax? Lineweaver-Burke Plot shift?Km is the same because the enzymes that still work retain their same affinity; Vmax is decreased; Lineweaver burke plot becomes steeper. this is when inhibitor binds to the allosteric site4
12982183361What is uncompetitive inhibition? Km & Vmax?inhibitor can only bind to the ES complex; Both Km & Vmax decrease5

12984538961Glucocorticoids (cortisol)create muscle breakdown22
13082607060What is the Hill coefficient?23
13083812505What is Kcat?- The number of molecules of substrate the enzyme turns into product per unit of time24
13083816191- Km vs Kd- Km can be found at Vmax/2; lower the Km, the higher the affinity - Kd measures the dissociation from the ES complex, so the larger the Kd is, the less affinity the enzyme has to that specific substrate25
13083819867- How does a noncompetitive inhibitor work?- It can bind to either the free enzyme or the ES complex, also considered a mixed inhibitor - No change in Km & decrease in Vmax26
13083822230- How does an uncompetitive inhibitor work?- It can bind to the ES complex - So decreases Vmax, because no matter how much substrate you add, you can't overcome the effects of the inhibitor27
13126618225How does an anion-exchange column work?It pulls anion's down28
13140929687Describe GPCR signalingGPCR's are found in eukaryotic cells & are 7 seven helices transmembrane proteins. When the receptor is inactive, it is bound to a GDP. When a ligand binds to the receptor, it binds to GTP and the receptor has a conformational change. Underneath are 3 subunits. GTP causes the alpha subunit to go off & bind to another protein, which then activates cAMP, which then starts a signal pathway29
