Which is the correct order of transport of protein in a secretory pathway?

8. Which is the correct order of transport of protein in a secretory pathway? Explanation: Protein synthesized in the cytoplasm-RER lumen-cis Golgi-median Golgi-trans Golgi-vesicles-fusion of vesicles with plasma membrane-exocytosis.

What is the order of the secretory pathway?

The secretory pathway comprises the rough endoplasmic reticulum (rough ER), ER exit sites (ERESs) the ER-to-Golgi intermediate compartment (ERGIC), the Golgi complex and post-Golgi carriers en route to their final destination.

How does the secretory pathway work?

The secretory pathway occurs in a vectorial manner and begins with uptake of amino acids that are used by the rough endoplasmic reticulum to produce newly synthesized proteins. These new proteins are transported to the Golgi complex for further processing and sorting.

What pathway is generally followed by a protein produced for secretion?

These experiments defined a pathway taken by secreted proteins, the secretory pathway: rough ER → Golgi → secretory vesicles → cell exterior. Further studies extended these results and demonstrated that this pathway is not restricted to proteins destined for secretion from the cell.

Which of the following is correct sequence route of the secretory product?

Answer. Proteins destined to be secreted move through the secretory pathway in the following order: rough ER → ER-to-Golgi transport vesicles → Golgi cisternae → secretory or transport vesicles → cell surface (exocytosis) (see Figure 17-13).

What is the pathway of a newly synthesized protein?

Newly synthesized proteins enter the endomembrane system through the endoplasmic reticulum. From there them move through the Golgi apparatus and into either the Secretory Pathway or the Lysosomal Pathway.

What is the process of protein secretion?

Protein secretion is a multistep process that involves vesicle biogenesis, cargo loading, concentration and processing, vesicle transport and targeting, vesicle docking and Ca2+-dependent vesicular fusion with the plasma membrane.

Which pathway is generally followed by a protein produced for secretion quizlet?

Proteins destined to be secreted move through the secretory pathway in the following order: rough ER → ER-to-Golgi transport vesicles → Golgi cisternae → secretory or transport vesicles → cell surface (exocytosis) (see Figure 17-13).

What is the sequence of events involved in the production of proteins that is secreted?

What is the sequence of events to produce a protein that is secreted? A hormone signals the gene that encodes the protein to be transcribed into mRNA in the nucleus. The mRNA is translated into protein on the ER, then processed and folded in the Golgi apparatus, and then sent out of the cell in a vesicle.

What do secretory proteins do?

Secretory proteins enter this set of interconnected organelles at the endoplasmic reticulum (ER), which regulates protein translation, protein translocation across the membrane, protein folding and post-translational modification, protein quality control, and forward traffic of suitable cargo molecules (both lipid and …

Which of the following correctly describes the pathway for how a protein is made and delivered in a cell?

So, the correct answer is ‘Rough ER →→ Golgi apparatus →→ Cell membrane’.

  • What is the path a secretory protein follows?

    Type I has just a signal peptide and then one stop transfer in the middle.

  • Type II does not start with a signal peptide.
  • Type III is like Type II – no signal peptide,just a signal anchor in the middle,but in this case the+++come after the hydrophobic sequence,which reverses
  • Which part of the cell produces secretory proteins?

    This conversion is carried out by enzymes, known as RNA polymerases, in the nucleus of the cell. What in the cell produces secretory proteins? Secretory proteins are synthesized by ribosomes attached to the cisternae of the endoplasmic reticulum and translocated to the lumen of the endoplasmic reticulum.

    What is the correct pathway of protein production?

    The secretory pathway occurs in a vectorial manner and begins with uptake of amino acids that are used by the rough endoplasmic reticulum to produce newly synthesized proteins. These new proteins are transported to the Golgi complex for further processing and sorting.
