One of the greatest challenges in teaching biology is helping students understand non-tangible cellular processes like energy utilization. The good news is ATP is the primary energy molecule for all life forms, which reinforces the importance of this molecule for cells to operate and maintain homeostasis. Despite ubiquitous dependence on ATP among life forms, there still seems to be a dearth of quality activities available to help students master comprehension of how the ATP-ADP cycle works.
My masters professor once said that educational studies show that it takes the average person/student something to the effect of twenty-six exposures - be it in the form of lecture to hands-on experiences - before true understanding of a new concept/topic occurs. As practitioners, we don't have the luxury of time or even available resources to offer that many exposures in the course of our limited time with students. Every available resource helps, which is why I published this activity. Most high school textbooks do a horrible job covering energy utilization at a cellular level.
The student version is one full page, front and back. I provided a two page color-coated answer key. The dumb thumbnail images kept misrepresenting my original document so I had to tweak my original so it would agree with the thumbnail images. That is why you will receive five extra pages - please delete them upon receipt. **ONLY KEEP PAGES 1-4 OF THIS DOCUMENT**
