The characterization of an enzyme usually includes the determination of key kinetic parameters. Indicate which of the following statements are true. (This is a multi- select question ). 0 KM is useful to when comparing different substrates, and how well they bind to the enzyme's active site. Kcat is a useful indicator of an enzyme's speed at 1/2 Vmax. Vmax is the maximal initial velocity of the enzyme when it is saturated with substrate. An enzyme is considered to approach "catalytic perfection" if it rarely makes an error. Enzymes are usually studied after boiling them in buffer, to remove the chance that contaminating microorganisms are responsible for the observed catalytic events.
