What is the function of the Golgi apparatus?

What is the function 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. Named after its discoverer, Camillo Golgi, the Golgi body appears as a series of stacked membranes.

What organelle makes lipids and carbohydrates?

smooth endoplasmic reticulum

What is the role of the Golgi apparatus in protein synthesis?

The Golgi apparatus transports and modifies proteins in eukaryotic cells. How have scientists studied dynamic protein movements through the Golgi? The Golgi apparatus is the central organelle mediating protein and lipid transport within the eukaryotic cell.

Does the Golgi apparatus process lipids?

In addition to its activities in processing and sorting glycoproteins, the Golgi apparatus functions in lipid metabolism—in particular, in the synthesis of glycolipids and sphingomyelin.

What does the Golgi apparatus secrete?

The Golgi apparatus is responsible for transporting, modifying, and packaging proteins and lipids into vesicles for delivery to targeted destinations. As the secretory proteins move through the Golgi apparatus, a number of chemical modifications may transpire.

What are the functions of SER and RER?

RER helps in the formation of proteins in the cell. The presence of ribosomes is actually responsible for the synthesis of the proteins by the RER….

RER-Rough Endoplasmic Reticulum SER-Smooth Endoplasmic Reticulum
Their function is to synthesize proteins. Their function is to synthesize lipids.

What is the structure of the smooth ER?

Smooth ER consists of a long network of a folded, tube-like structure. You can think of it like a pipeline with a lot of twists and turns. The interior of the smooth ER is called the lumen, which is enclosed by a phospholipid membrane, just like the membrane that encloses the entire cell.

Do prokaryotes have rough and smooth ER?

Instead, prokaryotic cells simply have an outer plasma membrane, DNA nucleoid structure, and ribosomes. Rough endoplasmic reticulum, peroxisomes, and mitochondria are all bound by their own plasma membranes, and are only found in eukaryotic cells.

What does Golgi body look like?

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 is the SER made of?

Smooth endoplasmic reticulum is found in both animal and plant cells and it serves different functions in each. The SER is made up of tubules and vesicles that branch out to form a network. In some cells there are dilated areas like the sacs of RER. Smooth endoplasmic reticulum and RER form an interconnected network.

Which organelle releases energy in a cell?

Mitochondria

What releases energy from a cell?

cellular respiration

Which produces a sugar called?

Photosynthesis is the process in which light energy is converted to chemical energy in the form of sugars. In a process driven by light energy, glucose molecules (or other sugars) are constructed from water and carbon dioxide, and oxygen is released as a byproduct.
