For students, one of the hardest concepts in biochemistry to grasp is the harvesting of electrons from glucose in cellular respiration.  Demonstrate how an instructor could create an assignment unique to this core content that specifically address two of the following four concepts:

1. What is a high energy electron?
2. What is an electron carrier (NAD+)?
3. How is the energy of the electron used to create a proton gradient?
4. How is a proton gradient used to phosphorylate ADP?

In , provide a quick summary of the assignment and applicable resources available, as well as critical-thinking questions, discussion questions, and/or potentially good short answer questions that could accompany the assignment you develop. 

APA style is not required, but solid academic writing is expected.
