please answer me this
Consider a membrane protein destined for the plasma membrane. From a hydropathy plot, you determine the protein has the following general structural elements: • • • 5 Trans-membrane domains (boxes 1-5) 6 soluble domains (wavy lines A-F) Flanking charges around trans-membrane domain 1. (A positive charge is towards the N-terminus, and a negative charge is towards the C-terminus.) You find that soluble domains B and E contain possible glycosylation sites. Ntorm in an ammo u arom...

You are interested in the mobility of two different unknown integral plasma membrane proteins—protein X and protein Y—in a cell. In one cell, you fluorescently label all the X proteins. In another cell, you label all the Y proteins. When you perform FRAP analysis on both cells, you find that most of the protein X fluorescence has recovered within 3 minutes, but recovery of the protein Y fluorescence is significantly slower. Even after 10 minutes, only 50% of the protein...

The nicotinic acetylcholine receptors are transmembrane protein found in the plasma membrane of human neurons. You are studying a member of the receptor family that is glycosylated. Based on this information, answer the following questions: Was the receptor synthesized on cytosolic ribosomes or ER-bound ribosomes? Justify your answer Describe the cellular path that the receptor likely took from synthesis to the plasma membrane.

Two different membrane preparations have been created from the plasma membrane of red blood cells (1) right-side-out membrane vesicles (ROVs) and (2) insideout membrane vesicles IOVs) in which the exoplasmic leaflet faces the interior of the vesicles. a. Annexin V is a protein that binds to phosphatidylserine, one of the phospholipids present in cell membranes. Fluorescently labeled annexin V is mixed with each vesicle preparation. The vesicles are washed to remove unbound annexin V and then examined by fluorescence microscopy....

QUESTION 9 Sequence analysis of a membrane protein shows four 20 amino acid long stretches of residues that are predominantly hydrophobic Between each of these stretches of hydrodophobic residues, a stretch of predominantly hydrophilic residues is found. From this observation one can reasonably postulate that: A this is a 4 stranded beta barrel which spans the membrane B.this is a glycoprotein o this protein has 4 alpha helical segments that span the membrane o this protein can be removed from...
