A biochemist has put in solution a protein with a very high molecular weight. The protein starts sedimenting.

a). Explain in words and illustrate with a drawing each of the 3 forces that act on the protein as it slowly moves towards the bottom of the flask with a terminal velocity. Gives the expression of each force and how they compensate each other.

Explain whether you expect the protein to sediment more quickly or more slowly if its shape goes from a spherical shape (soccer ball-like) to a prolate shape (American football-like).
