High energy electrons in cellular respiration

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 concepts:

1. What is a high energy electron?
2. What is an electron carrier (NAD+)?

 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.
