Based off your previous answer, how an extracellular molecule know the location of its receptor?

Still in progress. I've made these renders for showing purposes.

Inside a cell, large molecules are densely crowded so much so that the average distance between two macromolecules is typically less than the width of a single macromolecule

Most likely to not change much. I find the molecules to be vibrating a little too much, so I've...

An extracellular molecule knows the physical location of its receptor:

Color for the radar has been updated to a brighter color. Needs to re-render on AE but otherwise finalized.

Still fidgeting needed for False. Ligand might need to travel back and forth a few time bef...

Based on your previous answer and assuming there are several instances of the complementary receptor present, an extracellular molecule tries to move toward:

Ligand still looks like it is "thinking." Possible solution to rid of this motion is to remove any hovering art...

For the questions: An extracellular molecule tries to move towards a complementary receptor

Animations will most likely be set in stone as finals! woo hoo

 Version 2: Better ligand movement towards receptor 

Version 3 : More turbulance for the small molecules. Smoother ligand movement

Random version! S5Q4

What is the mechanism of an extracellular molecule’s movement towards a receptor

The extracellular molecule propels itself.

In the final version, the ligand would also be randomly rotating before it "propels" itself into the right position to situate in the receptor.
