State
The second law of thermodynamics holds that every energy transfer loses usable energy as heat, raising the universe's entropy, its measure of disorder.
Show
A cell's metabolic reactions lose energy as heat with every transfer, even as the cell itself stays highly ordered.
Watch for
A cell stays low-entropy locally only by exporting disorder outward — total entropy still rises.
