What is the difference between ER and Golgi apparatus?
The endoplasmic reticulum is involved in protein synthesis (RER) and lipid synthesis (SER), whereas the Golgi apparatus is involved in the packaging, transport and modification of proteins and lipids.
What is the function of Golgi body and endoplasmic reticulum?
Explanation: Golgy bodies helps in packaging of materials for inter and intracellular transport. In pants, materials of cell-plate are transported to the equator, while in animal it helps in liver cells. The endoplasmic reticulums are the sites of proteinsynthesis and give the cytoskeleton.
How do you distinguish between smooth and Golgi Apparlasmic reticulum?
What is the Difference Between Golgi Apparatus and Endoplasmic Reticulum? Golgi bodies or Golgi apparatus are an arrangement of few fluid-filled dishes whereas ER is a network of tubules and vesicles. Therefore, this is the key difference between Golgi apparatus and endoplasmic reticulum.
What is difference between rough ER and smooth ER?
The most basic difference between RER and SER is the presence of ribosomes. When ribosomes attach to the surface of an ER, it gives a characteristic rough appearance; hence it is called Rough ER. On the other hand, a smooth ER does not have ribosomes on its surface. It possesses ribosomes attached to its membrane.
What transports proteins to the Golgi apparatus?
vesicles
Proteins and other molecules are transported to the Golgi by packages called vesicles, which fuse with the outermost cisterna, which is known as the ‘cis-face’ of the Golgi, and unload their contents.
What is difference between smooth and rough ER?
When ribosomes attach to the surface of an ER, it gives a characteristic rough appearance; hence it is called Rough ER. On the other hand, a smooth ER does not have ribosomes on its surface. It possesses ribosomes attached to its membrane. It does not have ribosomes on its membrane.
How do proteins enter a cell?
Proteins destined for the nucleus contain NLSs. These short stretches of amino acids interact with proteins located in the cytoplasm, on the nuclear envelope, and/or at the nuclear pore complex. Following binding at the pore complex, proteins are translocated through the pore into the nucleus in a manner requiring ATP.
What color is the Golgi body?
red
| Organelle | Color (show) |
|---|---|
| Golgi | red |
| Rough ER | violet |
| Smooth ER | light green |
| Central Vacuole | violet |
How Golgi apparatus is formed?
Each Golgi stack is formed by five to eight tightly aligned flattened cisternae, which can be classified as three separate modules: the cis-Golgi network, which is close to the ER and receives the ER output, the stacked cis-, medial-, and trans-Golgi cisternae that contain glycosylation enzymes and process cargo …
How many Golgi apparatus are in a cell?
Similarly, the number of Golgi bodies in a cell varies according to its function. Animal cells generally contain between ten and twenty Golgi stacks per cell, which are linked into a single complex by tubular connections between cisternae.
What is the function of sER?
sER is a membrane-bound network of tubules (see Figs. 1-1 and 1-3) without surface ribosomes. sER is not involved in protein synthesis. Its main function is the synthesis of lipids, steroids, and carbohydrates, as well as the metabolism of exogenous substances, such as drugs or toxins.
