While much of the videos were way over my head, they were excellent tools for demonstrating the mechanisms that perform the complex operations essential to the cell being alive, and therefore that keep us alive. I was amazed by how seamlessly the cell functions despite the intense coordination that simple processes require. I'm curious to know - although I don't think I'd ever be able to really comprehend - the scale of a person's steps compared to the "steps" of the molecular machine carrying the mitochondria. The videos are definitely eye opening to all that's happening all the time beyond what meets the eye.
