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 in 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

Answer 1

The correct option is A B, C and D are correct.

The smooth endoplasmic reticulum forms a continuous system with rough endoplasmic reticulum. It consists of smooth membrane segments and is found in the regions of rich glycogen. It is related with peroxisomes. The functions of SER include mechanical support to the cells, exchange and translocation of substances, synthesis of lipoprotein, glycogen, etc. Ribosomes are involved in protein synthesis along with the RER. Mitochondria help in oxidative phosphorylation and generation of ATP through the Electron Transport Chain.

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