Question

Which of the following is not a characteristic of smooth endoplasmic reticulum?

• A. Ribosomes are present on its membrane
• B. Ribosomes are absent on its membrane
• C. Spherical structures that contain hydrolytic enzymes
• D. Involved in cellular respiration

Answer 1

The correct option is B

Ribosomes are absent on its membrane

Smooth endoplasmic reticulum is a network of tubular membranes within the cytoplasm of the cell, occurring either with a smooth surface and are devoid of ribosomes. The rough endoplasmic reticulum is studded with ribosomes. Lysosomes are spherical structures that contain hydrolytic enzymes. Mitochondria are involved in cellular respiration.
