Which cells have well developed smooth ER?

Which cells have well developed smooth ER?

Note: The smooth endoplasmic reticulum functions in many metabolic processes. It produces phospholipids, lipids for steroids and plasma membranes respectively. Cells that release these components, like the testes cells, ovaries, and skin oil glands, contain an extra of a smooth endoplasmic reticulum.

What type of cells need more smooth endoplasmic reticulum and why?

The two types of ER often appear as if separate, but they are sub-compartments of the same organelle. Cells specialising in the production of proteins will tend to have a larger amount of rough ER whilst cells producing lipids (fats) and steroid hormones will have a greater amount of smooth ER.

Which cells have well developed?

Cells which require to produce steroid hormones like Leydig Cells in males have well developed SER. Also hepatocytes(liver cells) have well developed SER to detoxify the drugs and harmful toxins.

Is the smooth ER found in prokaryotes?

Explanation: Prokaryotic cells are simple cells that lack membrane-bound nuclei and complex organelles. Endoplasmic reticulum, microtubules, and the Golgi apparatus are unique to eukaryotic cells, and will not be found in prokaryotes.

Where is the smooth endoplasmic reticulum located?

Smooth ER is prominent in cells of the liver that process harmful chemicals, in cells of the endocrine system such as those in the adrenals that produce steroid hormones, and in excitable cells such as neurons and muscle cells that use Ca 2+ signaling. Structure of the Smooth Endoplasmic Reticulum

What is the rough endoplasmic reticulum in a plant cell?

This is an electron microscope image showing part of the rough endoplasmic reticulum in a plant root cell from maize. The dark spots are ribosomes. There are two types of endoplasmic reticulum: rough endoplasmic reticulum (rough ER) and smooth endoplasmic reticulum (smooth ER). Both types are present in plant and animal cells.

Why is the smooth endoplasmic reticulum important for calcium storage and release?

The role of the smooth endoplasmic reticulum in calcium ion storage and release is of particular importance in the cells of the nervous and muscular system that use calcium-mediated signaling for excitation and contraction. Under resting conditions, the ER lumen can be partially full.

What is the function of ribosomes in the endoplasmic reticulum?

The rough endoplasmic reticulum has on it ribosomes, which are small, round organelles whose function it is to make those proteins. Sometimes, when those proteins are made improperly, the proteins stay within the endoplasmic reticulum.
