BCH 361 Ch. 7 TEST QUESTIONS
WITH CORRECT ANSWERS
Match the condition w/ the statement that describe it.
This condition will result in the highest rate.
A. [S]= 10Km
B. [S]= Km
C. [S]= 0.1Km - Answer-A

Match the condition w/ the statement that describe it.
Doubling [S] will have little effect on the rate.
A. [S]= 10Km
B. [S]= Km
C. [S]= 0.1Km - Answer-A

Match the condition w/ the statement that describe it.
About 90% of the active sites are occupies by substrate
A. [S]= 10Km
B. [S]= Km
C. [S]= 0.1Km - Answer-A

From the equation, when [S]= Km, Vo= - Answer-1/2 Vmax , Km equals to the [S] that
yields 1/2 Vmax

The larger the Km value, the weaker the interaction - Answer-
enzyme-substrate
Michaelis-Menten equation can be manipulated into one that yields a
plot. This double reciprocal equation is called .... - Answer-
straight-line; Lineweaver-burk equation

An enzyme works most efficiently with the substrate at concentration close to its Km,
when the rate .... - Answer-changes the most w/ a change in [substrate]

Substrate of the enzyme: chymotrypsin - Answer-acetyl-L-tryptophanamide

Substrate of the enzyme: lysozyme - Answer-Hexa-N-acetylglucosamine

Match the condition w/ the statement that describe it.
Doubling [S] will almost double the rate
A. [S]= 10Km
B. [S]= Km
C. [S]= 0.1 Km - Answer-C

Match the condition w/ the statement that describe it.
Half of the active sites are occupied by the substrate
A. [S]= 10Km
