I'm juggling three sources for my MCAT prep and ran into a discrepancy between the three on two topics dealing with enzyme inhibitors and Km Vmax.
1) EK says that for uncompetitive inhibitors Km and Vmax both decrease. Khan Academy says that Vmax decreases and Km stays the same. Who is correct?
2) BR and Khan only mention the "noncompetitive inhibitor category" and say that that Vmax decreases. EK agrees, BUT says that "noncompetitive inhibitors" are a subcategory of "Mixed inhibitors" and that a mixed inhibitor increases or decreases Km and decreases Vmax.
What do you think?
