Diffusion across the membrane is a theme that is covered by the fava beans. Fava beans produce free radicals that destroy red blood cells, and furthermore, it causes the cell membrane to burst. Based on my knowledge, a cell membrane burst because the solution outside is hypertonic, so the cells move out of the cell membrane causing them to burst. Therefore, free radicals are hypertonic to the cell membrane, and as the activity of free radicals increase, the faster the cell membrane burst, and the person die.
