What is the structure of the smooth endoplasmic reticulum?

What is the structure of the smooth endoplasmic reticulum?

The smooth endoplasmic reticulum comprises tube-like structure located near the cell periphery. These tubules or tubes sometimes branch forming a network that is reticular in appearance. The network of smooth endoplasmic reticulum allows for an increased surface area to be devoted to storage of key enzymes.

What are the functions of smooth ER?

Its main functions are the synthesis of lipids, steroid hormones, the detoxification of harmful metabolic byproducts and the storage and metabolism of calcium ions within the cell. The smooth ER is distinguished from the other parts of the endoplasmic reticulum by the absence of membrane-bound ribosomes.

What is the structure and function of endoplasmic?

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.

How is the structure of the endoplasmic reticulum related to its function?

The endoplasmic reticulum can either be smooth or rough, and in general its function is to produce proteins for the rest of the cell to function. The rough endoplasmic reticulum has on it ribosomes, which are small, round organelles whose function it is to make those proteins.

What is the function of rough and smooth endoplasmic reticulum in a plant cell?

The rough ER, studded with millions of membrane bound ribosomes, is involved with the production, folding, quality control and despatch of some proteins. Smooth ER is largely associated with lipid (fat) manufacture and metabolism and steroid production hormone production. It also has a detoxification function.

What are the functions of smooth and rough ER?

What is the function of smooth endoplasmic reticulum Class 9?

Smooth Endoplasmic Reticulum Function: Smooth ER is responsible for the synthesis of essential lipids such as phospholipids and cholesterol. Smooth ER is also responsible for the production and secretion of steroid hormones. It is also responsible for the metabolism of carbohydrates.

What is endoplasmic reticulum b describe its structure?

# ENDOPLASMIC RETICULUM : a network of membranous tubules within the cytoplasm of a eukaryotic cell, continuous with the nuclear membrane. It usually has ribosomes attached and is involved in protein and lipid synthesis. The general structure of theendoplasmic reticulum is a network of membranes called cisternae.

What is the structure of endoplasmic reticulum quizlet?

Rough endoplasmic reticulum has ribosomes attached to the cytoplasmic side of the membrane and the smooth endoplasmic reticulum lacks attached ribosomes. The smooth one is a tubule network and the rough one is a series of flattened sacs. Name of the space inside of the endoplasmic reticulum.
