Hint: Lysosomes are the membrane bound organelle that have the ability to break down the biomolecules like proteins, nucleic acid, lipids and carbohydrates. They contain some digestive enzymes that are capable of digesting food and other particles.
Complete step by step answer:
Lysosomes are the small organelle covered by the cell membrane whose membrane is made up of phospholipids. These are formed by the budding of the Golgi apparatus and the enzymes in the lysosomes are formed from the endoplasmic reticulum. Lysosomes secretes some acid hydrolases which are called as digestive enzymes that digest the food particles, viruses and bacteria enter into them, excess organelles and other macromolecules. They also digest their own cell too. This process is called autolysis which means killing of its own cell. This is also called by the name programmed cell death.
The lysosomes are acidic in nature since they secrete acid hydrolysis. Hence lysosomes secrete digestive enzymes. These organelles have the important role in the process of phagocytosis which means engulfing the particular organism and killing it. For example: The wide blood cells kill the invading antigen by engulfing it into its body.
So, the correct answer is “Option B”.
Note:
Lysosomes have many enzymes in it. It includes proteases, amylase, nuclease, lipase acid phosphatase etc. These enzymes are named by the molecules they breakdown. For example, the protease enzyme breaks down the proteins and the nucleic acid is broken down by the nuclease.
