Because the gram stain differentiates two types of bacteria based on the composition of their cell walls.
The only haploid cells found in humans are gametes
Electrons move through the electron transport chain from a higher to lower energy state. Energy release moves protons through channels in the membrane proteins, moving them into the inner membrane space. This leads to a buildup of positively charged protons, which creates an electrical potential across the membrane.
