Question

All the digestive enzymes like carbohydrates, proteases, lipases, DNase, RNase are found in?
A. Lysosome
B. Peroxisome
C. Glyoxysome
D. Vacuole

Answer 1

A cell is the unit of life. It has various organelles carrying out the functions of our life. From the protein synthesis to the import and export of materials from the cell, everything is organized in a cell. Some are membrane-bound while some are not. Their number varies from function and requirement.

Step by step answer: Out of the various big organelles in the cells like the Golgi apparatus, endoplasmic reticulum, there are small membrane-bound organelles which are of utter importance. They are like ribosomes, lysosomes, etc.
-Option A: Lysosome: They are the membrane organelles, formed from the Golgi apparatus. Their major function is to remove the waste from the cell. The autolysis is the process of destruction of a cell which is carried out by the lysosome. Thus the enzymes like DNase, RNase, protease, etc. are present in them to digest the macromolecules and nucleic acids.
-Option B: Peroxisome: They are found in the cytoplasm of all eukaryotic cells. They are the oxidative organelles. They generate hydrogen peroxide as their by-products.
-Option C: Glyoxysome: They are found in the plant cells and some of the fungi. They are used for the fat storage in filamentous fungi and germinating seeds. They have enzymes for pyrimidine synthesis, purine salvage, and ether lipid biosynthesis.
-Option D: Vacuole: They are the bubbles found in animal and plant cells, which store the food or nutrients. They can also have waste products to protect the cell from the contamination. There are a larger number of vacuoles in a cell. Their main function is to store nutrients and food.
So, the answer is option A: Lysosome

Note: Lysosomes are spherical structures. They have more than 40 types of enzymes in them. They have a variety of hydrolytic enzymes to break down the macromolecules. They are usually found in animal cells. They are rarely present in the plant cells.
