A mutation that inactivates an enzyme involved in the modification of sugars associated with glycoproteins is most likely to affect the function of which of the following cellular structures?
A)smooth ER
B)cisternae of the Golgi apparatus
C)transport vesicles produced by the rough ER
D)transport vesicles produced by the trans face of the Golgi apparatus

Question

Quizplus · Accepted Answer

The modification of sugars associated with glycoproteins occurs in the Golgi apparatus. Therefore, a mutation that inactivates an enzyme involved in this process is most likely to affect the cisternae of the Golgi apparatus where these modifications take place.
