A spherical cell with the diameter of 10uMhas a protein concentration of 20 mg/ml. Determine the number of protein molecules within the cell if the molecular weight of an average protein is 50,000 daltons (g/mol). Recall that Avogadro's number is N₁ = 6.0221367×1023 molecules/mol.
(c) The tube and cylinder diagram to the right illus- trates schematically the potassium channel protein from a bacterium. This channel protein consists of four identical polypeptide chains each comprised of 119 residues. The cyan ribbon illustrates only two of the polypeptide chains. The relative positions of 4 α-helices, one from each poly- peptide chain, are shown as cylinders. The red sphere in the central part of the diagram shows the position of a potas- sium ion identified by X-ray structure analysis. A cesium ion (green sphere) was also found to be stabilized in the same position when cesium chloride was introduced into the crys- tals. The cylinders each represent an α-helix running from Tyr62 to Thr74. Considering the position of the potassium ion, in- dicate on one of the cylinders at which end of the cylinder residue Tyr62 is found and at which end residue Thr74 is found. Explain the basis of your answer? Ala23 Thr119 (d) The N- and C-terminal residues of one of the…

The fosfomycin disc (200/50) also contains glucose-6-phosphate (G-6-P). Which ONE of the following best describes why this is the case? Select one: A. G-6-P increases the solubility of fosfomycin B. G-6-P is used to promote active transport of fosfomycin into the bacterial cell C. G-6-P is used in the formulation to correct glucose deficiencies promoted by fosfomycin D. G-6-P stabilises fosfomycin from spontaneous hydrolysis in aqueous solution E. G-6-P is an inhibitor of FosA that inactivates fosfomycin
