ATP, Episode 3

Page three of our story introduces the molecule in question. The goal here is to present the structure of ATP, the component parts and the fact that the phosphate groups carry negative charges. Having the characters count the charges may guide some readers to do the same and (perhaps) that interactive moment will help them internalize the information more thoroughly. Drawing the full structure of the ADP is meant to draw attention to the fact that it is exactly the same as ATP except for the phosphate group.

The last panel sets up an important moment in the explanation that parallels the character interaction between Wilbur and Harvey. My hope is that “humanizing” the coupling of the phosphate and ADP and employing some humor will underscore the idea that this is a highly reactive molecule. That will probably make more sense when I have the next page done…

You can read the story from the beginning in the ATP story post.
