Page five explains the mystery of the missing negative charge (whew, finally!) and underscores the role that the remaining negative charges play in making ATP a highly reactive molecule (note that ‘highly reactive’ is in bold on the page below, so it MUST be important). We also have an opportunity to for some character silliness and a shout out to the previous photosynthesis story. The pieces are all coming together. On the next page we meet a gigantic protein in the shape of…oh, wait. I don’t want to spoil it for you.
Once again, I appreciate the comments of Dr. Keeney’s Molecular Techniques course. They suggested that I point that the energy to assemble ATP comes from the food we eat. Thanks, kids, it is a good connection to make.
You can read the story from the beginning in the ATP story post.
