Question: What is the Golgi apparatus function?

The Golgi apparatus, or Golgi complex, functions as a factory in which proteins received from the ER are further processed and sorted for transport to their eventual destinations: lysosomes, the plasma membrane, or secretion. In addition, as noted earlier, glycolipids and sphingomyelin are synthesized within the Golgi.

What are the main functions of Golgi apparatus?

(i) The main function of Golgi apparatus is to carry out the processing of proteins generated in endoplasmic reticulum. Golgi apparatus also transports protein to the different parts of cell. (ii) The Golgi enzymes present in membranous disks of cisternae carry out the modification of cargo proteins.

What is the function and structure of Golgi apparatus?

The Golgi apparatus is a central intracellular membrane-bound organelle with key functions in trafficking, processing, and sorting of newly synthesized membrane and secretory proteins and lipids. To best perform these functions, Golgi membranes form a unique stacked structure.

What are the two main functions of the Golgi apparatus?

It has been likened to the cells post office. A major function is the modifying, sorting and packaging of proteins for secretion. It is also involved in the transport of lipids around the cell, and the creation of lysosomes. The sacs or folds of the Golgi apparatus are called cisternae.

Why is the Golgi apparatus the most important?

Why the Golgi Apparatus is THE most important organelle The Golgi Apparatus is important because it processes and packages protein and lipid. without the golgi apparatus you would lose your DNA, because DNA is composed of protein.

What is Golgi apparatus with diagram?

The Golgi apparatus, also called Golgi complex or Golgi body, is a membrane-bound organelle found in eukaryotic cells (cells with clearly defined nuclei) that is made up of a series of flattened stacked pouches called cisternae.

What is Golgi apparatus Class 9?

Golgi apparatus. Golgi apparatus. The stacks of flattened membranous vesicles are called Golgi apparatus. It basically stores, packs and modifies the products in vesicles. It temporarily stores protein that moves out of the cell through the vesicles of the Golgi apparatus.

How does the Golgi apparatus look?

The Golgi apparatus (GA), also called Golgi body or Golgi complex and found universally in both plant and animal cells, is typically comprised of a series of five to eight cup-shaped, membrane-covered sacs called cisternae that look something like a stack of deflated balloons.

What happens after the Golgi apparatus?

After the Golgi does its work on the molecules inside the sac, a secretory vesicle is created and released into the cytoplasm. From there, the vesicle moves to the cell membrane and the molecules are released out of the cell.

What body part is like the Golgi apparatus?

Lysosomes. the Golgi apparatus packages proteins inside the cell before they are sent to their destination. Like the Golgi apparatus, the heart packages nutrients and sends them off to the parts of the body that need it.

What would happen if the Golgi apparatus stopped working?

In the absence of the Golgi apparatus, lysosomes would not be produced, and the accumulation of dead and damaged organelles and molecules in the cell would ultimately result in cell death. If the Golgi apparatus is not present the packaging and transport of materials would cease.

What are the two main function of ribosomes?

A ribosome, formed from two subunits locking together, functions to: (1) Translate encoded information from the cell nucleus provided by messenger ribonucleic acid (mRNA), (2) Link together amino acids selected and collected from the cytoplasm by transfer ribonucleic acid (tRNA).

What is the main function of lysosomes?

Lysosomes function as the digestive system of the cell, serving both to degrade material taken up from outside the cell and to digest obsolete components of the cell itself.

What is the main function of ribosomes in translation?

Ribosomes translate information encoded in messenger ribonucleic acid (mRNA). They link together specific amino acids to form polypeptides and they export these to the cytoplasm. A mammalian cell may contain as many as 10 million ribosomes, but each ribosome has only a temporary existence.

What are the 3 functions of lysosomes?

A lysosome has three main functions: the breakdown/digestion of macromolecules (carbohydrates, lipids, proteins, and nucleic acids), cell membrane repairs, and responses against foreign substances such as bacteria, viruses and other antigens.
