Consider the membrane vesicle containing a protein oriented

Consider the membrane vesicle containing a protein oriented with its head in the outside monolayer. The vesicle can be microinjected into the cell. If the vesicle fuses with the membrane listed below, what would be the resulting orientation of the vesicle proteins? Assume that fusion occurs with conservation of the membrane asymmetry that already exists.
(a) injection into cytoplasm before fusion with plasmalemma
(b) injection into ER lumen then found in first Golgi cisterna

Solution

No picture given.

ER work as union of most lipids; combination of proteins for dissemination to numerous organelles and to the plasma layer while Golgi mechanical assembly have different capacities in cell framework as: vesicles from ER combine with Golgi , structure membranous sacs (cisternae) , alteration, arranging, pressing of proteins and lipids for either emission or conveyance to another organelle, oligosaccharide alteration ,vesicle docking/combination, vesicle must perceive and dock with amend target layer then the film can meld and the objective atoms conveyed , vesicles must have correlative protein receptors on target films ,vesicles moved forward and backward into zones where they are required

a pathway taken by emitted proteins, the secretory pathway: unpleasant ER Golgi secretory vesicles cell outside. This exhibited the pathway isn\'t confined to proteins bound for emission from the cell. Plasma film and lysosomal proteins additionally go from the unpleasant ER to the Golgi and after that to their last goals. Still different proteins go through the underlying strides of the secretory pathway yet are then held and capacity inside either the ER or the Golgi mechanical assembly.
