Question - You will do some "back of the envelope" calculations to become more familiar with the relative size of molecules, macromolecules, and cells. The answer to each question is worth five points. It is absolutely critical to show your work. Any response that provides only an answer with no indication of how the answered was arrived at will earn a grade of zero. Remember that these questions do not require precise answers. They should be arrived at via rough estimations where necessary and rounding to approximate values.
1) How many average-sized proteins can fit in a mitochondrion?
2) If a plant cell and its contents were enlarged to be the size of Ross Ade Stadium, how big would a water molecule be?
3) When an average-sized protein molecule is dissolved in water, approximately how many molecules of water does it make contact with?
