Which of the following statements is not correct?
Answer: (D) Lysosomes are formed by the process of packaging in the endoplasmic reticulum. Answer: (D) Lysosomes are formed by the process of packaging in the endoplasmic reticulum Solution: Lysosomes are formed by the process of packaging in the golgi apparatus, not the endoplasmic reticulum, so statement 4 is not correct and is the required answer.
- A.Lysosomes have numerous hydrolytic enzymes
- B.The hydrolytic enzymes of lysosomes are active under acidic pH
- C.Lysosomes are membrane bound structures
- D.Lysosomes are formed by the process of packaging in the endoplasmic reticulum✓
Correct Answer
(D) Lysosomes are formed by the process of packaging in the endoplasmic reticulum
Solution & Explanation
Answer: (D) Lysosomes are formed by the process of packaging in the endoplasmic reticulum Solution: Lysosomes are formed by the process of packaging in the golgi apparatus, not the endoplasmic reticulum, so statement 4 is not correct and is the required answer. Statements 1, 2 and 3 are correct: lysosomes are membrane-bound and rich in hydrolytic enzymes that are optimally active at acidic pH. NCERT Reference: Ch 8, p.96, lines 25–29: "These are membrane bound vesicular structures formed by the process of packaging in the golgi apparatus. The isolated lysosomal vesicles have been found to be very rich in almost all types of hydrolytic enzymes (hydrolases – lipases, proteases, carbohydrases) optimally active at the acidic pH."
