Question

Which sequence correctly traces the path of a protein in the cell?

Answer 1

Answer:

a. rough endoplasmic reticulum, Golgi apparatus, released from the cell

Explanation:

In an eukaryotic cell, the rough endoplasmic reticulum RER is a part of a continous membrane organelle within the cytoplasm who pricncipal role is synthesis of protein. So, the RER typically functions as protein synthesis

Also, the RER is located nearer to the Golgi Apparatus. The function of this Golgi Appparatus is to modify, package and transport these synthesized protein for delivery to their targeted destination where they will be of use (i.e  released from the cell)

Answer 2

Answer: Option a is the correct answer.

Explanation: Rough cytoplasmic reticulum is a membrane bound organelle to which ribosomes are attached. The ribosomes on the surface of the rough endoplasmic reticulum are organelles where protein synthesis takes place in a process called translation. The rough endoplasmic reticulum then transports the newly synthesized proteins to the golgi apparatus where they undergo posttranslational modification and packaged into vesicles. After modification and packaging, the newly synthesized proteins are then released from the cell and transported to where they are needed.
