Above is a diagram of an electron transport chain. Below you will consider two scenarios where mutations have occurred that altered the functions of the components.  1. If a mutation destroyed the ability of protein I to pump protons, how would that impact ATP generation and why? (4 points) 2. If a mutation destroyed the ability of protein I to transfer electrons, how would that impact ATP generation and why? (4 points)
