The Maximum Rate I At Which Oxygen Molecules Can Be Consumed By A Bacterium Or Radius R In A Lake Where The Concentratio 1 (58.25 KiB) Viewed 56 times

The maximum rate I at which oxygen molecules can be consumed by a bacterium or radius R in a lake where the concentration of oxygen is co = 0.2 mole m-3 increases with the first power of R. We might expect the oxygen consumption, however, to increase roughly with an organism's volume. Together, this statements imply an upper limit to the size of a bacterium: If R gets too large, the bacterium would literally suffocate. The actual metabolic activity of a bacterium is about 0.02 mole kg! sl. What limit do you then get on the size of a bacterium? Compare to the size of a real bacteria. Can you think of some way for a bacterium to evade this limit?
