An Abundance of Energy. All cells need energy to function, but muscle cells have unusually high energy requirements. They resist the force of gravity, generate heat by shivering, pump blood, move substances through hollow organs and produce strong bodily movements.This vigorous activity is powered by organelles known as mitochondria.n Abundance of Energy.
