Options
- AStatements I, II and III are correct
- BStatements I, III and IV are correct
- CStatements II, III and IV are correct
- DOnly statements I and II are correct
Correct answer
A. Statements I, II and III are correct
Step-by-step solution
The endoplasmic reticulum (ER) divides the intracellular space into two distinct compartments: luminal (inside the ER) and extra-luminal (cytoplasm). Thus, statement I is correct. The rough endoplasmic reticulum (RER) bears ribosomes on its surface and is continuous with the outer membrane of the nucleus. Thus, statement II is correct. The smooth endoplasmic reticulum (SER) is the major site for the synthesis of lipids. In animal cells, lipid-like steroidal hormones are synthesised in the SER. Thus, statement III i
