Question

1. explain the important roles played by peroxisomes. 27. use peroxisomes as an example to explain the value of compartmentalization in cells.

Explanation:

1. Peroxisomes play roles such as breaking down fatty - acid molecules through beta - oxidation, detoxifying hydrogen peroxide into water and oxygen, and participating in lipid biosynthesis.
2. Peroxisomes compartmentalize reactions involving highly reactive oxygen - containing compounds. This separation protects other cell components from damage by these reactive substances and allows for the efficient and specialized functioning of these reactions within the peroxisome.

Answer:

1. Peroxisomes break down fatty acids via beta - oxidation, detoxify hydrogen peroxide, and contribute to lipid biosynthesis.
2. Peroxisomes compartmentalize reactive oxygen - related reactions, protecting other cell parts and enabling efficient specialized function.
