Which of the following features correctly describe aspects of protein structure? a) A protein possessing disulfide bonds will be more stable than a protein with the identical primary sequence lacking disulfide bonds. O b) B-sheets can only be formed from the anti-parallel arrangement of B-strands. O c) Folding of a protein (tertiary structure) will typically result in a majority of the non-polar amino acids being distributed on the protein surface. d) both a and c

Asymmetrical distribution of membrane phospholipids in cytosolic versus extracellular leaflets of the plasma membrane is largely due to... the tendency of hydrophobic phospholipids to avoid the extracellular fluid by flipping to the inner membrane leaflet. scramblase enzymes in the ER that catalyze the movement of phosphatidyl b) serine and phosphatidyl ethanolamine (PS, PE) from cytosolic to non-cytosolic membrane leaflets. scramblase enzymes in the plasma membrane that catalyze the movement of phosphatidyl serine and phosphatidyl ethanolamine (PS, PE) from outer to inner membrane leaflets. flippase enzymes in the Golgi apparatus that catalyze the movement of d) phosphatidyl serine and phosphatidyl ethanolamine (PS, PE) from one membrane leaflet to the other. e) both b and d are true.
