AP Bio Enzymes Quiz

(a)   are the substances that enzymes act on.

When the enzyme and substrate bind together the enzyme is called (a)   .

A solution tha has a pH of 2 is how many times more acidic than one with a pH of 5?

• 1000

• 500

• 10

• 30

Which of the following will least affect the effectiveness of an enzyme?

• temperature

• pH

• Concetation of the enzyme

• original activation energy

Which of the following is a process similar to competitive inhibition?

• You arrive at work and you are unable to park in your assigned parking spot because the person next to you has parked over the line and your car won't fit.

• You arrive at work and are unable to par your car in your spot because there is already a car parked there.

• As you are pulling in to your parking spot a bulldozer pushes the car out of it's space.

• When you arrive to work you cannot enter the parking lot because the gate is locked.

In noncompetitive inhibition

• the inhibitor binds to a different part of the enzyme causing a change of shape.

• the inhibitor binds to the active site of the enzyme causing a change of shape

• the substrate bind to the active site.

• the substrate and inhibitor are the same shape.

The induced fit model of the enzyme-substrate interaction can possibly overcome competitive inhibition by

• increasing concentration of the substrate.

• decreasing concentration of the substrate.

• increasing the concentration of the enzyme.

• changing the active site.

(a)   are proteins that act as organic catalysts.
