Question

Which of the following cell organelles stores hydrolytic enzymes?
(a) Centriole
(b) Lysosome
(c) Chromoplast
(d) Chloroplast

Answer 1

Hint: They are membrane- bound organelles present within the cell. They are also referred to as the suicidal bag of the cell. They remove and degrade undesirable products from the cell.

Complete answer:
Lysosomes are membrane- bound organelles that store the hydrolytic enzymes that have the potential to interrupt many sorts of biomolecules. The important function of lysosomes is digestion and removal of waste. The breakdown and recycle cellular debris, discarded cellular contents, and foreign pathogens, however, the digestive enzymes may end up bursting from the lysosome, damaging the cell themselves, and this will cause the cell to die.
- Lysosomes comprise over 50 different enzymes. They're synthesized within the rough endoplasmic reticulum.
- Once synthesized, the enzymes are brought in from the Golgi body in tiny vesicles or sacs, which then merge with bigger acidic vesicles.
- The enzymes produced especially for lysosomes are mixed with the molecule mannose 6- phosphate making them get fixed appropriately up into acidified vesicles.
- Lysosomal storage diseases are metabolic disorders, which are recognized by an accumulation of macromolecules. These macromolecules contain toxic materials, undigested particles of the cell, etc. - These macromolecules accumulate due to the shortage of enzymes within the Lysosome.
So, the correct answer is ‘Lysosomes’.

Note: Only eukaryotic animal cells contain lysosomes. Prokaryotic cells, like bacteria, don't contain lysosomes or any of the other membrane- bound organelle. The term was coined by Christian de Duve, a Belgian biologist, who discovered it and ultimately got a Nobel Prize in Medicine or Physiology in the year 1974.
