Which of the following sequences represent a possible pathway in the production of a secretory protein?

Options

  1. ARough ER ⟶\longrightarrow Secretory vesicle ⟶\longrightarrow Ribosome ⟶\longrightarrow Golgi apparatus
  2. BRibosome ⟶\longrightarrow Rough ER⟶E R \longrightarrow Golgi apparatus ⟶\longrightarrow Secretory vesicle
  3. CSecretory vesicle ⟶\longrightarrow Golgi apparatus ⟶\longrightarrow Ribosomes ⟶\longrightarrow Rough ER
  4. DRough ER ⟶\longrightarrow Ribosomes ⟶\longrightarrow Secretory vesicles ⟶\longrightarrow Golgi apparatus

Correct answer

D. Rough ER ⟶\longrightarrow Ribosomes ⟶\longrightarrow Secretory vesicles ⟶\longrightarrow Golgi apparatus

Step-by-step solution

Ribosome are the place where protein synthesis takes place →\rightarrow rough ER produces proteins and helps them fold properly →\rightarrow Golgi bodies does packaging of proteins →\rightarrow secretory vesicles does transport of proteins.
