What is the role of smooth endoplasmic reticulum?

What is the role of smooth endoplasmic reticulum?

The smooth endoplasmic reticulum functions in many metabolic processes. It synthesizes lipids, phospholipids as in plasma membranes, and steroids. The smooth endoplasmic reticulum also carries out the metabolism of carbohydrates and steroids.

How do smooth ER help maintain homeostasis?

The cellular lipids synthesized by the sER provide the cell with membrane lipids essential for the growth and differentiation‐based changes in morphology and structure of the cell. They also help to maintain the membrane homeostasis across the cell.

How can smooth endoplasmic reticulum detoxify drugs and poisons?

The detoxification process is performed by the help of the smooth endoplasmic reticulum in liver cells. Liver cells are composed of enzymes that catalyse a number of reactions and can make lipid-soluble drugs and metabolic wastes which are soluble in water, so that these can easily be passed out from the body.

Is smooth endoplasmic reticulum prokaryotic or eukaryotic?

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.

How do you make a smooth endoplasmic reticulum model?

Roll your clay into a ball that is approximately 3 inches wide. Press it down onto a smooth surface to begin forming the smooth, endoplasmic reticulum. Push your rolling pin onto the clay and roll it until you have a vertically rectangular sheet about 1/4-inch thick. Pull if off your table to prevent it from sticking.

Why is the smooth endoplasmic reticulum associated with fats?

Smooth E R (SER) is associated with the production and metabolism of fats and steroid hormones. It is ‘smooth’ because it is not studded with ribosomes and is associated with smooth slippery fats. To view a micrograph of ER interpreted using the Gridpoint cross-hairs device, click here.

What types of substances are detoxified in the smooth endoplasmic reticulum?

The smooth ER converts organic substances into water and other soluble products to allow for excretion. Large amounts of smooth ER are found in liver cells, where products of natural metabolism, drugs, and alcohol are detoxified.

What is the major detoxification related objective of the smooth endoplasmic reticulum?

Explanation: One of the most important and main functions of Smooth Endoplasmic Reticulum is detoxification, which is the removal of all the toxic materials such as (metabolic wastes or drugs).

What do smooth ER and rough ER have in common?

Both rough ER and smooth ER have the same types of membranes but they have different shapes. Rough ER is called rough because it has ribosomes attached to its surface. The double membranes of smooth and rough ER form sacs called cisternae. Protein molecules are synthesized and collected in the cisternal space/lumen.

What is the function of the smooth endoplasmic reticulum?

Then there’s the smooth endoplasmic reticulum, which doesn’t have those ribosomes on it. And that smooth endoplasmic reticulum produces other substances needed by the cell. So the endoplasmic reticulum is an organelle that’s really a workhorse in producing proteins and substances needed by the rest of the cell.

What are the variants of endoplasmic reticulum?

Endoplasmic Reticulum Diagram. The below diagram shows the variants of endoplasmic reticulum: Rough ER. Smooth ER. Rough endoplasmic reticulum has ribosomes embedded within its structure, giving a “rough” appearance. Smooth endoplasmic reticulum does not have these ribosomes, hence appear “smooth.”. Endoplasmic Reticulum diagram.

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.

What is the function of smooth ER in cell membrane?

It participates in the production of phospholipids, the chief lipids in cell membranes and are essential in the process of metabolism. Smooth ER transports the products of the rough ER to other cellular organelles, especially the Golgi apparatus.
