What is the main difference between the ER and the Golgi apparatus?

What is the main difference between the ER and the Golgi apparatus?

Difference Between Endoplasmic Reticulum and Golgi Apparatus Cisternae in ER are interconnected with each other, facilitating the transport of macromolecules throughout the cell. In contrast, the cisternae in Golgi apparatus contains four to six small cisternae. They are not interconnected with each other.

What is the relationship between endoplasmic reticulum and the Golgi apparatus?

Vesicles that bud off from the ER fuse with the closest Golgi membranes, called the cis-Golgi. Molecules then travel through the Golgi apparatus via vesicle transport until they reach the end of the assembly line at the farthest sacs from the ER — called the trans-Golgi.

What is the relationship between Golgi apparatus and the ER in a protein secreting cell?

The Golgi apparatus is often found in close proximity to the ER in cells. Protein cargo moves from the ER to the Golgi, is modified within the Golgi, and is then sent to various destinations in the cell, including the lysosomes and the cell surface.

How is the Golgi body formed?

She says that the Golgi makes itself from scratch. According to her theory, packages of processing enzymes and newly made proteins that originate in the ER fuse together to form the Golgi. As the proteins are processed and mature, they create the next Golgi compartment. This is called the cisternae maturation model.

How do nucleolus and ribosomes work together?

In the nucleolus, new ribosomal RNA combines with proteins to form the subunits of the ribosome. The newly made subunits are transported out through the nuclear pores to the cytoplasm, where they can do their job.

What is the biggest difference between prokaryotic and eukaryotic cells?

The primary distinction between these two types of organisms is that eukaryotic cells have a membrane-bound nucleus and prokaryotic cells do not. Prokaryotes, on the other hand, have no membrane-bound organelles. Another important difference is the DNA structure.
