Quick Answer: What Is The Full Form Of SER And RER?

What is the full form of SCR?

A silicon controlled rectifier or semiconductor controlled rectifier is a four-layer solid-state current-controlling device..

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.

What is the major functional difference between SER and RER?

The main difference lies between the SER and RER is the presence of ribosomes, as SER do not have ribosomes but RER have ribosomes. SER mainly produce and export lipids and protein and function for detoxification, while RER produces, secrete and export proteins and few hormones.

What is the function of Ser Class 9?

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.

What is the function of nucleus?

The nucleus controls and regulates the activities of the cell (e.g., growth and metabolism) and carries the genes, structures that contain the hereditary information. Nucleoli are small bodies often seen within the nucleus.

What is full form of Triac?

A TRIAC (triode for alternating current; also bidirectional triode thyristor or bilateral triode thyristor) is a three terminal electronic component that conducts current in either direction when triggered. … The bidirectionality of TRIACs makes them convenient switches for alternating-current (AC).

What is the difference between SER and RER?

The most basic difference between RER and SER is the presence of ribosomes….Difference between Smooth and Rough Endoplasmic Reticulum.Rough Endoplasmic Reticulum (RER)Smooth Endoplasmic Reticulum (SER)Provides proteins and lipids for Golgi apparatus.Provides vesicles for cis-face of Golgi apparatus.7 more rows

What do you mean by ER?

Emergency RoomBiology and medicine. Emergency Room, the emergency department in a medical facility specializing in acute, emergency care, usually found in a hospital or other primary care center. Endoplasmic reticulum, a type of organelle in cell biology.

What’s the difference between rough and smooth ER?

Rough ER looks like sheets or disks of bumpy membranes while smooth ER looks more like tubes. Rough ER is called rough because it has ribosomes attached to its surface. … Smooth ER (SER) acts as a storage organelle. It is important in the creation and storage of lipids and steroids.

What is the function of Golgi body?

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.

What is the function 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 ReticulumSER-Smooth Endoplasmic ReticulumTheir function is to synthesize proteins.Their function is to synthesize lipids.6 more rows

What are the types of SCR?

Types of ThyristorsSilicon controlled thyristor or SCRs.Gate turn off thyristors or GTOs.Emitter turn off thyristors or ETOs.Reverse conducting thyristors or RCTs.Bidirectional Triode Thyristors or TRIACs.MOS turn off thyristors or MTOs.Bidirectional phase controlled thyristors or BCTs.Fast switching thyristors or SCRs.More items…

How SCR is used as a switch?

When connected to a direct current DC supply, the thyristor can be used as a DC switch to control larger DC currents and loads. When using the Thyristor as a switch it behaves like an electronic latch because once activated it remains in the “ON” state until manually reset. Consider the DC thyristor circuit below.

What is the full form of RER?

Rough endoplasmic reticulum (RER), series of connected flattened sacs, part of a continuous membrane organelle within the cytoplasm of eukaryotic cells, that plays a central role in the synthesis of proteins.

What are the main function of endoplasmic reticulum?

The endoplasmic reticulum (ER) is a large, dynamic structure that serves many roles in the cell including calcium storage, protein synthesis and lipid metabolism. The diverse functions of the ER are performed by distinct domains; consisting of tubules, sheets and the nuclear envelope.
