1. How does an uncompetitive inhibitor affect Vmax, Km, and the lineweaver burke plot?

Uncompetitive inhibitors make the enzyme substrate complex so stable that it won't release the substrate. This means you need less substrate to reach half of vmax, which means Km is lowered. Uncompetitive Inhibitors cannot be outcompeted at high concentrations of substrate, which means that the vmax of the enzyme is lowered. The lineweaver Burke Plot for an uncompetitive inhibitor will have a higher y-intercept with a left shift of the x-intercept. The decrease in km and vmax is proportional, so the new inhibition line will have the same slope as the uninhibited one.
In this step, 1 CO2 and 1 NADH are produced per 1 molecule of Pyruvate (remember, Glycolysis creates 2 Pyruvates that both fall down this pathway).
Ketogenesis occurs in the mitochondria of liver cells.
States that enzymes are like locks and substrates are like keys, and an appropriate match allows them to interact.
