Lysosomes are membrane-enclosed organelles that contain an array of enzymes capable of breaking down all types of biological polymers—proteins, nucleic acids, carbohydrates, and lipids.

In cell biology, a vesicle is a structure within or outside a cell, consisting of liquid or cytoplasm enclosed by a lipid bilayer. If there is only one phospholipid bilayer, they are called unilamellar liposome vesicles; otherwise they are called multilamellar.

Function and Types of Vesicles There are essentially four types of vesicles used by cells. They are vacuoles, lysosomes, transport vesicles, and secretory vesicles. Vacuoles are vesicles that contain mostly water.

The correct answer is option d, a lysosome is a specialized vesicle that is called the ‘recycling center’ of the cell because it contains digestive…

Because a vesicle is essentially a small organelle, the space inside the vesicle can be chemically different from the cytosol. It is within the vesicles that the cell can perform various metabolic activities, as well as transport and store molecules.

The secretory vesicle is a vesicle that mediates the vesicular transport of cargo – e.g. hormones or neurotransmitters – from an organelle to specific sites at the cell membrane, where it docks and fuses to release its content.

Secretory vesicles form from the trans Golgi network, and they release their contents to the cell exterior by exocytosis in response to extracellular signals. The secreted product can be either a small molecule (such as histamine) or a protein (such as a hormone or digestive enzyme).

Lysosomes are membrane-bound organelles with roles in processes involved in degrading and recycling cellular waste, cellular signalling and energy metabolism. Defects in genes encoding lysosomal proteins cause lysosomal storage disorders, in which enzyme replacement therapy has proved successful.

Lysosomes are vesicles that contain digestive enzymes. They are only present in animal cells. They function as part of the cell’s recycling system and can also help initiate cell death. When a cell needs to recycle large molecules, lysosomes release their enzymes to break down these bigger molecules into smaller ones.

Transport vesicles. Transport vesicles help move materials,such as proteins and other molecules,from one part of a cell to another.

All cells do not contain the same types of enzymes. All cells contain exactly the same number of enzymes. All cells contain exactly the same types of enzymes. All cells do not contain enzymes.

Lysosomes contain various hydrolytic enzymes (around 50 different enzymes) that are capable of digesting nucleic acids , polysaccharides , lipids , and proteins. The inside of a lysosome is kept acidic as the enzymes within work best in an acidic environment.
