Lysosomes are the reservoirs of

Explanation

• Lysosomes are membrane-bound vesicle-like structures that are rich in hydrolytic enzymes like lipases, hydrolases, and carbohydrases.
• These enzymes are active at acidic pH, and degrade foreign pathogens and worn out and dead cell components. Thus, lysosomes function as a digestive system of the cell.
• Lysosomes are also commonly referred to as suicidal bags of the cell.
• Option A is incorrect, as adipose tissue, beneath our skin, is the reservoir of fats and provides insulation to the body.
• RNA is present in the cell's nucleolus and helps translate genetic information.
• Glycoproteins get synthesized in the endoplasmic reticulum and Golgi apparatus of the cell. The Carbohydrate core gets attached to the protein chain, (glycoprotein =carbohydrate + protein).

Final Answer

Hence, the correct option is D i.e., Hydrolytic enzymes.
