It's quite a few below for some effects. Have you heard of the double slit experiment? But actually the scale of cells and their structures is macro-molecule scale... a lot of the behaviour of those things (DNA, proteins etc..) is very quantum mechanical.. there are also structures working with ions and even protons (hydrogen ion) in there.
