Why does the Golgi apparatus have a large surface area?

The number of Golgi cisternae as a function of total Golgi membrane surface area A′ as it increases due to the arrival of a large amount of discoid membrane. This provides a larger scale representation of Figure 7 when the membrane arrives in the form of discs.

Why does endoplasmic reticulum have large surface area?

The many tubules that the ER packs into certain places in the cell also produce a large surface area. This could allow the ER to provide the space for making lipids, folding proteins and storing important molecules until they are needed.

Does the Golgi apparatus have a large surface area?

Golgi apparatus of both plant and animal cells are characterized by an extensive system of approximately 30 nm diameter peripheral tubules. The total surface area of the tubules and associated fenestrae is thought to be approximately equivalent to that of the flattened portions of cisternae.

Why does the endoplasmic reticulum have folds?

Protein folding is optimized in the ER. These chaperone proteins bind to the new proteins as they enter the lumen through the translocon and in addition to simply preventing incorrect bonds that would have to be broken, they also prevent premature interaction of multiple polypeptides with one another.

Which organelle has the most surface area?

The ER has the largest surface area of any subcellular organelle and is the site where most proteins and lipids are first inserted into a membrane.

What is the purpose of the Golgi apparatus?

A Golgi body, also known as a Golgi apparatus, is a cell organelle that helps process and package proteins and lipid molecules, especially proteins destined to be exported from the cell.

What organelle has the largest surface area?

The ER has the largest surface area of any subcellular organelle and is the site where most proteins and lipids are first inserted into a membrane. New lipids and proteins leave the ER for other sites by vesicle-mediated transport.

Why do the endoplasmic reticulum and Golgi apparatus work together to synthesize molecules?

Ribosomes are bound to the membrane of rough ER. The translated proteins are exported into the ER for maturation. These proteins are again transported into Golgi apparatus for further maturation and sorting out for their final destination. Therefore, both ER and Golgi apparatus are involved in protein maturation.

How do the endoplasmic reticulum and the Golgi complex work together explain?

The Golgi complex works closely with the rough ER. When a protein is made in the ER, something called a transition vesicle is made. This vesicle or sac floats through the cytoplasm to the Golgi apparatus and is absorbed. From there, the vesicle moves to the cell membrane and the molecules are released out of the cell.

Why is it important that a cell have a large surface area relative to its volume?

Smaller single-celled organisms have a high surface area to volume ratio, which allows them to rely on oxygen and material diffusing into the cell (and wastes diffusing out) in order to survive. The higher the surface area to volume ratio they have, the more effective this process can be.
