| Comments |
"If one considers the measured lateral diffusion constant of rhodopsin in the membrane plane (5×10^-9 cm^2/sec) (primary sources) and the average separation, collision theory shows that a rhodopsin must collide every 5-10µsec with a neighboring rhodopsin." Research in primary sources conducted on frog and mud puppy. |
