Question

Quizplus · Accepted Answer

The diameter of a typical globular protein is on the order of nanometers, about ten million times smaller than a tennis ball, which has a diameter on the order of centimeters. Ten million multiplied by the diameter of a typical animal cell (10 to 20 micrometers) yields 100 to 200 meters, comparable to the dimensions of a stadium. It should be noted that a plant cell can be 200 µm across, corresponding to the size of a town in our analogy; on the other hand, a bacterium at 2 µm would be only as large as a tennis court.
