Which of the following correctly describes the pathway taken by a protein destined for secretion from an animal cell?
A)plasma membrane → transport vesicle → Golgi → transport vesicle → rough ER
B)Golgi → rough ER → transport vesicle → plasma membrane
C)rough ER → transport vesicle → lysosome → transport vesicle → plasma membrane
D)rough ER → transport vesicle → Golgi → transport vesicle → plasma membrane
E)rough ER → transport vesicle → Golgi → transport vesicle → lysosome → plasma membrane

Question

Quizplus · Accepted Answer

The correct pathway for a protein destined for secretion from animal cells is from rough ER to transport vesicle to Golgi to transport vesicle to plasma membrane. Option A is incorrect because the transport vesicle goes from rough ER to Golgi and then to plasma membrane. Option B is incorrect because the Golgi is after the rough ER in the secretory pathway. Option C is incorrect because lysosomes are involved in intracellular digestion and not protein secretion. Option E also includes lysosomes in the secretory pathway, which is incorrect.
