Detailed explanation-1: -So, the correct answer is ‘Rough ER →→ Golgi apparatus →→ Cell membrane’.
Detailed explanation-2: -These experiments defined a pathway taken by secreted proteins, the secretory pathway: rough ER → Golgi → secretory vesicles → cell exterior.
Detailed explanation-3: -Proteins from the ER are transported to the ER-Golgi intermediate compartment and then enter the Golgi apparatus at the cis Golgi network. They then progress to the medial and trans compartments of the Golgi stack, within which most metabolic activities of the Golgi apparatus take place.
Detailed explanation-4: -Answer and Explanation: Although the protein itself is not made until the mRNA transcript leaves the nucleus to find a ribosome in the cytosol or on rough endoplasmic reticulum, the most correct choice is A) nucleus, ribosome, Golgi apparatus.
