One of the most important pathways in USMLE Step 1 is the TCA Cycle. In the Biochemistry section TCA Cycle is well explained. I found this video online which explains the cycle very well. What I love about these medical videos is that if the teacher goes too fast you can pause, rewind to watch again, and absorb the information before going to the next concept. On top of that, you are learning from the understanding of instructor on the video so, you don’t have to guess what you’re learning. Of course, you should know the details of the TCA cycle and you should start from page 1 in Biochemistry.
This video is just an example of how videos can enhance the understanding of medical concepts.
