For each of the following statements, indicate whether it is true of all, some, or none of the various kinds of peroxisomes. Please first answer the question, then provide an explanation. I would appreciate it if you could type the answer and handwriting is often difficult to read.

5. Contains peroxide-generating chemical reactions.
a. It is true of all, because it is general property of peroxisomes.
b. It is true of glyoxysomes and some animal peroxisomes, because only they contain peroxide-generating chemical reactions.
c. It is true of none of the peroxisome kinds.

6. Contains the genes coding for luciferase.
a. It is true of all because all peroxisomes contain the genes coding for luciferase.
b. It is true of glyoxysomes and some animal peroxisomes, because only they contain the genes coding for luciferase.
c. It is true of none of the kinds, because fireflies and related bioluminescent organisms have luciferase protein present in their peroxisomes but DNA is not found in this organelle.

7. Contains urate oxidase.
a. It is true of all because all peroxisomes contain urate oxidase.
b. It is true of many animal peroxisomes and in some plant peroxisomes.
c. It is true of none of the peroxisome kinds.

8. Is a source of dolichol.
a. It is true of all because all peroxisomes are a source of as much as 50% of the dolichol found in cells.
b. It is true of glyoxysomes and some animal peroxisomes, because only they are source of dolichol.
c. It is true of none of the peroxisome kinds.

9. Is surrounded by a lipid bilayer.
a. It is true of all, because it is general property of peroxisomes.
b. It is true of glyoxysomes and some animal peroxisomes, because only they are surrounded by a lipid bilayer.
c. It is true of none of the peroxisome kinds.

5. Option a is the correct answer.

Peroxisomes contains peroxide-generating chemical reactions because it is a general property of peroxisomes. They are specialized to carry out oxidative reactions using the molecular oxygen. Peroxisomes generate hydrogen peroxide with the help of catalase enzyme and use it for oxidative purposes.

6. Option c is the correct answer.

Peroxisomes are organelles that do not possess DNA to contain genes in it like mitochondria and chloroplast. So, peroxisomes do not contain the genes that code for luciferase.

7. Option b is the correct answer.

Peroxisomes are present in all eukaryotic cells, animal peroxisomes has enzymes like xanthine oxidase and urate oxidase and in plant peroxisomes urate oxidase is present in some one of which is the peroxisomes that are isolated from the maize root tip contained urate oxidase. So, it is true of many animal peroxisomes and in some plant peroxisomes.

8. Option a is the correct answer.

Peroxisomes are involved in lipid synthesis. They synthesize cholesterol and dolichol. It is true of all because all peroxisomes are a source of as much as 50% of the dolichol found in cells because most of the dolichol is synthesized in peroxisomes only they contain elevated concentrations of sterol carrier-protein 2, which stimulates dolichol synthesis.

9. Option a is the correct answer.

Peroxisomes are surrounded by a lipid bilayer.
