Is endoplasmic reticulum in an animal cell?

Is endoplasmic reticulum in an animal cell?

The endoplasmic reticulum (ER) in animal cells is an extensive, morphologically continuous network of membrane tubules and flattened cisternae. Many of these functions are not homogeneously distributed throughout the ER but rather are confined to distinct ER subregions or domains.

What is the function of smooth endoplasmic reticulum in animal cell?

The smooth ER is involved in the synthesis of lipids, including cholesterol and phospholipids, which are used in the production of new cellular membrane. In certain cell types, smooth ER plays an important role in the synthesis of steroid hormones from cholesterol.

Is endoplasmic reticulum in plant and animal cells?

Endoplasmic reticulum is an organelle found in both eukaryotic animal and plant cells. It often appears as two interconnected sub-compartments, namely rough ER and smooth ER. Both types consist of membrane enclosed, interconnected flattened tubes.

What does the endoplasmic reticulum do in the animal cell?

Beside this, what does the endoplasmic reticulum do in the animal cell? The smooth endoplasmic reticulum, or smooth ER, is an organelle found in both animal cells and plant cells. An organelle is a sub-unit within a cell that has a specialized function. The main function of the smooth ER is to make cellular products like hormones and lipids.

Is endoplasmic reticulum prokaryotic or eukaryotic?

The endoplasmic reticulum is an organelle that can be found in both eukaryotic and prokaryotic cells. Just keep in mind that not all cells have endoplasmic reticulum! For example, red blood cells don’t have endoplasmic reticuli, even though they’re an important part of animal biology.

What is the role of rough endoplasmic reticulum in protein folding?

Rough endoplasmic reticulum also plays a vital role in protein folding. Also ensures quality control (regarding correct protein folding). The second most important function after protein synthesis and protein folding is protein sorting.

What is the structure of the smooth endoplasmic reticulum?

Smooth Endoplasmic Reticulum Structure 1 The smooth endoplasmic reticulum, on the other hand, does not have ribosomes. 2 The smooth endoplasmic reticulum has a tubular form. 3 It participates in the production of phospholipids, the chief lipids in cell membranes and are essential in the process of metabolism.
