Question

a. Calculate the approximate volumes of a water molecule, fatty acid synthase, the foldsome, ribosome, and hemoglobin. Clearly state any assumptions you have made to calculate the volume. Give all volumes in units of Å³. b. A typical E. coli cell (left) is cylindrical with dimensions of 2 x 1 microns, while a typical liver cell (right) has dimensions of 100 microns and is spherical. Calculate the volumes of each of these cells. How many E. coli could fit into 1 liver cell? c. How many E. coli cells laid end to end would fit across the diameter of a pin head? (Assume a pinhead diameter of 0.5 mm.) d. An E. coli cell contains about 15,000 ribosomes. What fraction of the E. coli cell volume is occupied by ribosomes?
