"...So, the cell’s currency for being able to use ATP is dependent upon us being able to synthesize huge amounts of ATP and recycle ADP into ATP and AMP into ADP and, um, ATP as well."

I literally spent 20 minutes trying to transcribe this sentence out and figure out what in the world this guy was trying to say. I think mainly, the confusion was caused by his absolute butchering of the definition of the word currency. And the roundabout way he talks.
Worse, that last chunk about AMP and ADP and ATP, he trailed off in a mumble. It was quite frustrating.

I can live without professors with communication problems, speech disorders, and a large vocabulary that they do not utilize correctly.
