State two functions each of the endoplasmic reticulum, the Golgi apparatus and the lysosome.
Original Khojo Papers practice question — not from a past board paper.
Answer
The rough endoplasmic reticulum synthesises proteins and transports them; the smooth kind synthesises lipids and detoxifies drugs. The Golgi apparatus modifies, packages and secretes proteins, and forms lysosomes. Lysosomes digest worn-out organelles and foreign material and, on rupture, can digest the whole cell.
No citable source has been recorded for this record. Treat it as practice material, not as fact.
Explanation
Lysosomes are sometimes called the suicide bags of the cell.
