What type of organic molecule is produced by smooth ER?
smooth endoplasmic reticulum (SER), meshwork of fine disklike tubular membrane vesicles, part of a continuous membrane organelle within the cytoplasm of eukaryotic cells, that is involved in the synthesis and storage of lipids, including cholesterol and phospholipids, which are used in the production of new cellular …
What are two types of molecules made in the smooth endoplasmic reticulum?
Two types of fat molecules made in the smooth ER are steroids and phospholipids. Steroids are made in the cells of the adrenal and endocrine glands. Smooth endoplasmic reticulum has varied roles depending on the type of cells it is found in. In brain and muscle cells, it plays a role in carbohydrate metabolism.
What molecules are manufactured by the smooth ER quizlet?
The smooth endoplasmic reticulum is another organelle in eukaryotic cells that synthesizes lipids. This organelle is located near the rough endoplasmic reticulum, and it produces phospholipids and cholesterol that help stabilize the membranes of the entire cell.
Does smooth ER produce protein?
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 ER enlist types of ER?
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. The two types of ER often appear as if separate, but they are sub-compartments of the same organelle.
What are the types of ER based on the morphology?
The ER can be classified in two functionally distinct forms: smooth endoplasmic reticulum (SER) and rough endoplasmic reticulum (RER). The morphological distinction between the two is the presence of protein-synthesizing particles, called ribosomes, attached to the outer surface of the RER.
What is the smooth ER quizlet?
smooth endoplasmic reticulum. collection of enzymes that perform specialized tasks, including synthesis of membrane lipids and the detoxification of drugs. endoplasmic reticulum. site where lipid components of the cell membrane are assembled, along with proteins and tother materials that are exported from the cell.
Does smooth ER contain its own molecules of DNA?
The smooth ER contains its own molecules of DNA. Hypercholesterolemia is an inherited disease in which the body’s cells lack the protein receptors that bind to cholesterol-delivering LDLs. Ribosomes consist of two subunits, each surrounded by a membrane.
What organelle makes proteins?
ribosomes
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 other organelles does the smooth endoplasmic reticulum work with?
Endoplasmic Reticulum – Wrapping it Up It works closely with the Golgi apparatus, ribososmes, mRNA, and tRNA.
How is the smooth ER different from the rough ER?
The smooth ER is a continuous extension of the rough ER, located more distally from the nucleus. Whereas the rough ER is shaped like flattened hollow pancakes in many cell types, the smooth ER is usually more tubular in structure, forming a lacelike reticulum.
What is the function of the smooth ER membrane?
The lumen of the smooth ER also serves as an important storage site for intracellular Ca2+. Smooth ER membranes contain ligand-regulated Ca2+ channels that open in response to the hormone-generated second messenger inositol 1,4,5-triphosphate (IP3 ).
Why is the smooth endoplasmic reticulum engorged?
They’re retained and the endoplasmic reticulum becomes engorged because it seems to be constipated, in a way, and the proteins don’t get out where they’re suppose to go. Then there’s the smooth endoplasmic reticulum, which doesn’t have those ribosomes on it.
What is the function of smooth ER in the adrenal cortex?
Smooth ER is also involved in the production of steroid hormones in the adrenal cortex and endocrine glands. Smooth ER also plays a large part in detoxifying a number of organic chemicals converting them to safer water-soluble products.
