What is the function of an endoplasmic reticulum?
What is the function of an endoplasmic reticulum?
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 meaning of endoplasmic?
Endoplasmic reticulum (ER), in biology, a continuous membrane system that forms a series of flattened sacs within the cytoplasm of eukaryotic cells and serves multiple functions, being important particularly in the synthesis, folding, modification, and transport of proteins .
What is the definition of reticulum?
1 : the second compartment of the stomach of a ruminant in which folds of the mucous membrane form hexagonal cells — compare abomasum, omasum, rumen. 2 : a reticulate structure : network.
What are organelles definition?
: a specialized cellular part (such as a mitochondrion, chloroplast, or nucleus) that has a specific function and is considered analogous to an organ.
What is another name for reticulum?
The reticulum is colloquially referred to as the honeycomb. It is also known as the bonnet and as the kings-hood. When cleaned and used for food, it is called “tripe”.
What is reticulum composed of?
Rough endoplasmic reticulum (rER) is composed of a membrane (ER) that is a continuation of the nuclear envelope and ribosomes. Ribosome, mRNA, tRNA, and enzymes may associate free in cytoplasm and make proteins. Cells use this format when synthesizing cytoplasmic proteins.
What is the meaning of rumen?
The rumen, also known as a paunch, is the largest stomach compartment in ruminants and the larger part of the reticulorumen, which is the first chamber in the alimentary canal of ruminant animals. …
What is the main function of the Abomasum?
The main function of the abomasum is to digest protein from both feed and ruminal microbes. Gastric juices, produced in abomasum, accomplish this.
Why is Abomasum called a true stomach?
Abomasum The abomasum is the fourth stomach compartment. It is also called the “true stomach”. It is here that the cow’s own stomach acids and enzymes are used to further breakdown ingested feed before it passes into the small intestine.
Why does the cow have 4 stomachs?
Answer: Cows are true ruminants, which means they have four stomachs, the first of which is the rumen. When the cow swallows the bolus for the second time, it is finer and settles at the bottom of the rumen. The rumen contracts, forcing some of this well-chewed food into the second stomach, or reticulum.
What animals have 2 stomachs?
Ruminants and camelids are a group of animals that have stomachs with multiple compartments.
What did giraffes used to be called?
Cervus camelopardalis
