Question:

Which of the following statements is not correct?

Lysosomes have numerous hydrolytic enzymes

The hydrolytic enzymes of lysosomes are active under acidic pH

Lysosomes are formed by the process of packaging in the endoplasmic reticulum

Lysosomes are membrane bound structures

Solution:

Correct option is D. Lysosomes are formed by the process of packaging in the endoplasmic reticulum. Lysosomes bud off from the trans face of Golgi bodies. Precursor of lysosomal enzymes are synthesized by RER and then sent to Golgi bodies for further processing. So, the correct answer is 'Lysosomes are formed by the process of packaging in the endoplasmic reticulum'.
