Which sequence correctly traces the path of a protein in the cell?
a)ribosome, re reticulum, golgi apparatus release from cell
b) ribosome, se reticulum, golgi apparatus, chlroplast
c)se reticulum, ribosome, golgi apparatus, released from cell
d) mitochondria, re reticulum, cell membrane

The question says,'which sequence traces the path of a protein in the cell? The correct option is A. In the cell, ribosome handles the synthesis of proteins. After protein synthesis, the proteins are transported to the rough endoplasmic reticulum and from there to the golgi apparatus which excrete unwanted proteins from the cell.

The sequence that correctly traces the path of a protein in the cell is; ribosome, RE reticulum, Golgi apparatus, release from cell.

Further Explanation. Protein synthesis  Protein synthesis takes place in organelles called ribosomes. The synthesis of proteins occurs through a process known as translation. During translation codes are decode for specific amino acids that are then joined to form proteins. Path traced by protein Ribosomes Ribosomes are organelles on the surface of the rough endoplasmic reticulum where the synthesis of proteins takes place through the process of translation. After translation proteins are then passed to the endoplasmic reticulum. Rough endoplasmic reticulum This a type of membrane-bound organelle which undertakes the role of protein synthesis, transport, modification and folding.  Rough endoplasmic reticulum plays an important role in protein synthesis from the instructions contained in DNA. Golgi apparatus  From the endoplasmic reticulum, the proteins are then passed to the Golgi apparatus which is a system of membranes responsible for modification, processing and packaging of proteins inside the vesicles.  Golgi apparatus packages the protein in a secretory vesicle, which then fuses with the cell membrane and releases the protein from the cell.
