Question

Compare and contrast the role of secretory vesicles, the lysosome, and the peroxisome.

Answer 1

Lysosomes ( common in animal cell but rare in plant cells) contain hydrolytic enzymes necessary for intracellular digestion in white blood cells that eat bacteria) lysosomes contents are carefully released Into the cytoplasm can also cause cell death.  

Peroxisomes: this organelle is responsible for protecting the cell form its own production of toxic hydrogen peroxide. As an example, white blood cells produce hydrogen peroxide to kill bacteria .The oxidative enzymes in peroxisomes break down the hydrogen peroxide into water and oxygen.

Secretory vesicles: cell secretions –e.g, hormones, neurotransmitters, are packaged in secretory vesicles at the Golgi apparatus. The secretory vesicles are then transported to the cell surface for releases.  

Answer 2

Answer:

Lysosomes are spherical pouches that have digestive enzymes. It allows the digestion of bacteria, viruses or some toxins, they also allow the breakdown of glycogen and the release of thyroid hormone, they also break down the bone allowing the release of calcium.

While secretory lysosomes are located in white blood cells, in immune cells such as melanocytes.

On the other hand, peroxisomes are membranous sacs that are made up of oxidases and catalases. They are responsible for neutralizing free radicals and free radicals from highly reactive chemicals.
