A) hydrolytic enzymes
B) secretory glycoproteins
C) RNA and protein
D) fats (or sugars or ATP)
Correct Answer: A
Solution :
Lysosomes were discovered by Christian de Duve (1955) from rat liver. Matile (1964) discovered lysosomes in plants. Generally lysosomes are 0.2 - 0.8 n in size, irregular membranous vesicles filled with hydrolytic enzymes. They are polymorphic. About 40 enzymes (all hydrolytic) are present in lysosomes. These include proteases, nucleases, glycosidases, lipases, phospholipases, phosphatases and sulfatases.
