Have you ever wondered just what goes on inside the cells in your body? These animations show components including the energy-producing mitochondria, the structural filaments and microtubules, the incredible walking kinesins that traverse them, and the nucleus packed with tightly coiled DNA. Surrounding the nucleus we watch as the ribosomes of the rough endoplasmic reticulum produce proteins, which are sent to the Golgi apparatus for labelling and release. We see lipids being manufactured in the smooth endoplasmic reticulum, and the various proteins and channels that are embedded in the cell’s membrane. All produced by Mike DeSantis.
