Slide 9 of 32
Notes:
The first graph I show is for the concentration profile around a cell that is taking up a limiting nutrient, because many of you may be familiar with this type of graph.
Most of the graphs in this talk are non-dimensionalized, with radial distance scaled to cell radius, and concentration scaled to the far-field or surface concentration.
Here, the cell is a ‘perfect absorber’, that is, every nutrient molecule that comes near the cell is taken up, and the concentration at the cell surface is 0 mol L-3.
You can see the concentration declines towards the cell as a function of 1/r.
