Answer:
The oligosaccharide is assembled on the lipid carrier at the membrane of the ER
Explanation:
N-linked glycosylation consists of the attachment of an oligosaccharide (glycan) to a nitrogen atom of the asparagine (Asn) residue in the protein. N-linked glycosylation is a key posttranslational modification (PTM) capable of controlling protein structure and function, this pathway takes place in the plasma membrane in archaea organisms and in the membranes of the endoplasmic reticulum (ER) in eukaryotic organisms. In eukaryotic cells, the N-linked glycosylation conserved pathway consists of two steps. In the first place, the oligosaccharides are assembled on a lipid carrier called dolichyl pyrophosphate localized in the endoplasmic reticulum (ER). The dolichyl-phosphatase is a hydrolase enzyme that acts on phosphoric monoester bonds. Second, the oligosaccharides are modified by specific glycosyltransferases that transfer these molecules to selected Asparagine (Asn) acceptor residues of polypeptide chains that have entered the lumen of the ER. These N-glycans are firstly assembled as a dolichol-linked precursor oligosaccharide at the cytoplasmic face of the ER.
Answer:
Some members of each group unicellular (& some colonial & some w/multicellular stages in life cycle)
-Mostly microscopic
No germ layer present
Specialized organelles; (found nucleus single or multiple, no organs or tissues)
-Free living, mutualism, commensalism, parasitism all represented in groups
-Locomotion by pseudopodia, flagella, cilia, & direct cell movements; some sessile
-Some provided w/simple endoskeleton or exoskeleton, but most naked
-Nutrition of all types
-Aquatic or terrestrial habitat
-Reproduction asexually by fission, budding, & cysts and sexually by conjugation or syngamy (union of male & female gametes to form zygote)
Explanation:
A.Long term energy storage
It is important to go through a fluid phase as it is being produced because the object must go through heat to be melted and then it should be put into a mold to be formed. Also, it go though heat to keep it from cracking and go to be cooled and harden. Hope this answers the question. Have a nice day.
