What type of enzymes are present in the lysosomes? What is their function? Which cell organelles manufacture these enzymes?

(N/A) $(i)$ Lysosomes contain powerful digestive enzymes known as hydrolytic enzymes.
$(ii)$ These enzymes are capable of breaking down all organic materials. Thus, they help to keep the cell clean by digesting foreign materials as well as worn-out cell organelles.
$(iii)$ The Rough Endoplasmic Reticulum $(RER)$ is responsible for manufacturing these enzymes.
