Question

When lysosomes burst, they release their enzymes and digest entire cell. It is called

• A. Autolysis
• B. Autophagy
• C. Endocytosis
• D. Exocytosis

Answer 1

Answer: (A)

Autolysis

A. Autolysis, also known as self-digestion, is the breakdown or destruction of a cell due to action of its own enzymes. It is seen in Lysosomes.

B. Autophagy is a mechanism of intracellular degradation in which cytoplasmic constituents are delivered to the lysosomes where they are degraded.

C. Endocytosis is a cellular process in which substances are taken into the cell by the invagination of membrane.

D. Exocytosis is a cellular process in which substances are secreted from the cell in transport vesicles.

Lysosomes release their enzymes and digest entire cell due to which they are known as 'suicide bags' and this process is known as Autolysis.

So, the correct answer is 'Autolysis'.
