Let's, for example, take a ribosome. It is an enzyme that is in turn just a molecule that must follow the laws of physics.
Correct me if I'm wrong, but it can be looked upon as a molecular machine made up of several pieces. What exactly makes those pieces work together?
Why does the ribosome bind to a strand of RNA? Is it just the shape and electric charge or is it something more? Once the ribosome is bound to a piece of RNA, how does it move?
In a way, I'm looking for the "ghost in the machine". I'm interested in molecules in general, not just ribosomes. What is it that, on a level of single atoms, makes molecules "alive" - move, assemble a protein, etc. ?
Let me give a hypothetical example:
Imagine a strand of carbons. Also imagine that there exists a molecule that can move along this strand. How would it do it? What forces would move it along this strand? Is it electromagnetism? Would gravity be involved to a significant degree? What effect would shape have?
