What is the first step in the secretory pathway?

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 is the pathway of a newly synthesized secretory protein in a cell?

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.

What do secretory proteins do?

A secretory protein is any protein, whether it be endocrine or exocrine, which is secreted by a cell. Secretory proteins include many hormones, enzymes, toxins, and antimicrobial peptides. Secretory proteins are synthesized in the endoplasmic reticulum.

What is the most common pathway taken by a newly synthesized proteins that will be secreted by a cell?

Function of the secretory pathway. The most common secretion pathway is the secretory pathway (Figure 1). Newly synthetized proteins are transported from the endoplasmic reticulum (ER), passing the Golgi apparatus and packed into vesicles. The vesicles are then transported to the plasma membrane.

Which is the correct pathway of a protein through a cell as it is being made 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 path of a protein through the Endomembrane system?

Transport through the endomembrane system Most proteins are then transported to the Golgi apparatus in membrane vesicles. Some proteins, however, need to stay in the ER and do their jobs there. The protein with its final set of carbohydrate chains is then transported to the plasma membrane in a transport vesicle.

Which of the following correctly describes the pathway taken by a protein destined for secretion?

Answer: The pathway taken by a protein for secretion is C) rough ER → transport vesicle → Golgi → transport vesicle → plasma membrane.

Which of the following is the correct path of a transport protein from the rough endoplasmic reticulum to the plasma membrane?

Golgi apparatus
Rough ER → Golgi apparatus → Cell membrane.

What transports proteins around the cell?

The Golgi apparatus
The Golgi apparatus transports and modifies proteins in eukaryotic cells.

Which is the final organelle of the secretory pathway?

The secretory pathway, beginning from the initial targeting of secreted and membrane proteins to the endoplasmic reticulum (ER), transit through the Golgi, and finally on to organelles like the lysosome or the plasma membrane, has been well characterized in mammalian cells and in simple organisms like yeast (Schekman.

What is the common pathway taken by a synthesized protein that will be exported by the cell?
