You are isolating cell fractions using a variety of centrifuge techniques.You have two very similar fractions but at this point are unable to discern which fraction is peroxisomes and which is lysosomes.As a result,you need to test the fractions for unique enzyme activities.If you are looking for peroxisomes,one enzyme activity you can test for is
A)hexokinase.
B)ATPase.
C)glucose-6-phosphatase.
D)cytochrome c oxidase.
E)catalase.
