Question

Consider the following statements and select the correct option.
(A) The endomembrane system includes plasma membrane, ER, Golgi complex, Lysosomes and vacuoles.
(B) ER helps in the transport of substances, synthesis of proteins, lipoproteins and glycogen.
(C) Ribosomes are involved in protein synthesis.
(D) Mitochondria help on oxidative phosphorylation and generation of ATP.

• A. (B), (C) and (D) are correct
• B. (A) alone is correct
• C. (B) alone is correct
• D. (C) alone is correct
• E. (D) alone is correct

Answer 1

The correct option is A (B), (C) and (D) are correct

ER helps in the transport of substances, synthesis of proteins, lipoproteins and glycogen, Ribosomes are involved in protein synthesis and Mitochondria help in oxidative phosphorylation and generation of ATP. However the endomembrane system includes plasma membrane, ER, Golgi complex, Lysosomes but not vacuoles. Thus vacuoles are not a part of the endomembrane system of the cell.

So the correct option is '(B), (C) and (D) are correct'.
