Question

Quizplus · Accepted Answer

Milk secretion involves the synthesis of milk proteins and lipids in the endoplasmic reticulum (ER) and Golgi apparatus. The synthesized molecules are then packaged into vesicles and transported to the cell membrane for secretion. The process starts with the nucleus providing the genetic material for protein synthesis in the ER, then moves to the Golgi apparatus for modification and packaging, and finally to the vesicles for transport to the cell membrane for secretion. Therefore, the correct sequence is nucleus -> ER -> Golgi apparatus -> vesicles -> cell membrane. Option B correctly reflects this sequence.
