Cell Biology Homework

timer Asked: Sep 10th, 2015

Question description

Recent estimates conclude that macromolecules occupy approximately 25% of the volume of a cell. A rod-shaped prokaryotic E. coli cell has dimensions 2 micrometers long X 0.5 micrometers in diameter. Assume, for the sake of simplicity, that the macromolecules occupying the cell are all globular proteins of 4 nm diameter. How many of these protein molecules would be found in 25% of the bacterial volume? Show calculations.
