Q:

What is the function of the Golgi apparatus?

A:

Quick Answer

The Golgi apparatus is responsible for identifying, processing and packaging macromolecules. The Golgi apparatus does not create macromolecules, nor does it assist with the macromolecules' functions. Instead, it acts like a courier and simply transfers the macromolecules to the appropriate destination.

Full Answer

The Golgi apparatus is an organelle found in DNA-carrying eukaryotic cells. It is one of the largest structures inside the cell. The Golgi apparatus resembles a long, thin ribbon folded on top of itself to create a long, layered central part with curved edges on either end. These internal layers are known as the cisternae, and their size and shape depend on the type of cell. Cisternae found in animal cells typically have 10 to 20 layers, while the cisternae of single-cell organisms often have 60 layers.

The macromolecule enters the Golgi apparatus at one of the curved ends. It traces its way through the layers of cisternae while being sorted and refined by the Golgi apparatus. At the end of the cisternae maze, the macromolecule enters a transport vessel and is shipped to the appropriate destination.

According to a 2009 study by Daniel Ungar, malfunctions in the Golgi apparatus and its cisternae are tied to inheritable diseases, such as muscular dystrophy, as well as diabetes and several forms of cancer.

    What is the function of endoplasmic reticulum?

    A:

    In addition to other jobs, the endoplasmic reticulum creates and folds proteins and then carries these synthesized substances to the Golgi apparatus via the vesicles. The endoplasmic reticulum also executes sorting activities for the cell's proteins. However, the precise duties carried out by the endoplasmic reticulum vary by both species and cell type.

    What is the function of ribosomes?

    A:

    Ribosomes are responsible for protein synthesis in a cell by translating messenger RNA, or mRNA, into amino acid chains. Ribosomes exist in the cell's fluid component and are bound to the rough endoplasmic reticulum.

    What is an organelle that modifies and packages proteins?

    A:

    The organelle that modifies and packages proteins is the Golgi apparatus. This organelle comprises several flattened sacs called cisternae. The Golgi apparatus, also called the Golgi body or Golgi complex, has two sides or faces, the cis face and the trans face, as described in "The Cell: A Molecular Approach."

    What is the packaging and distribution center of the cell?

    A:

    The Golgi apparatus is known as the packaging and distribution center of the cell. Named after the physician who discovered it in 1898, the Golgi apparatus is found in both plant and animal cells. The Golgi apparatus is also called the Golgi body or the Golgi complex.
