      28. What are the morphological, chemical and functional similarities and differences between lysosomes and peroxisomes?
      Similarities: lysosomes and peroxisomes are small membranous vesicles that contain enzymes and enclose residual substances from internal or external origin degrading them. Differences: lysosomes have digestive enzymes (hydrolases) that break substances to be digested into small molecules; peroxisomes contain enzymes that degrade mainly long-chained fatty acids and amino acids and that inactivate toxic agents including ethanol; within peroxisomes there is the enzyme catalase, responsible for the oxidation of organic compounds by hydrogen peroxide (H2O2) and, when this substance is in excess, by the degradation of the peroxide into water and molecular oxygen.

      I can give more details on various enzymes and stuff if you like…? Make a comment if you have a more specific question or if you need an explanation of the terminology or something.

      Please don’t just copy questions from the Internet – it’s boring! Your own questions are much more interesting.
