AP BIO ENZYME CHAPTER 6 QUIZ
QUESTIONS WITH CORRECT
ANSWERS
Which of the following statements is correct?
-enzymes fit into the active site on the surface of the substrate
-substrates fit into the active site on the surface of an enzyme
-substrate are larger than enzymes
-enzymes have completely smooth surfaces - ANSWER-Substrates fit into the active
site on the surface of an enzyme
Denaturation... - ANSWER-1. changes the shape of the enzyme
2. prevents that enzyme from binding with its substrate molecules efficiently
3. occurs at temperatures above a certain point
Which of the following could be used to increase the reaction rate beyond the point
of saturation?
-increase the amount of substrate
-decrease the amount of substrate
-increase the enzyme concentration
-decrease the enzyme concentration - ANSWER-increase the enzyme concentration
A group of AP Biology students are testing the effect of temperature on catalase
activity in cells. In cells, catalase breaks down hydrogen peroxide (H202) into water
(H20) and oxygen gas (02). Which of the following is the enzyme in this experiment?
-the enzyme is hydrogen peroxide
-the enzyme is a catalase
-the enzyme is water
-the enzyme is oxygen gas - ANSWER-the enzyme is a catalase
Using the graph, which of the following identifies an appropriate dependent variable
in this experiment?
-the dependent variable is time
-the dependent variable is the presence of amylase
- the dependent variable is the rate of reactin
- the dependent variable is the absence of amylase enzyme - ANSWER-the
dependent variable is the rate of reaction
Identify all the things that are generally expected to increase the rate of an enzymatic
reaction? - ANSWER--add more enzyme
-add more substrate
- denature the enzyme
