This learning project allows participants to explore some of the details of energy storage molecules and biological energy storage that involves ion gradients across cell membranes.

How do humans store energy?

Under normal circumstances, though, humans store just enough glycogen to provide a day's worth of energy. Plant cells don't produce glycogen but instead make different glucose polymers known as starches, which they store in granules. In addition, both plant and animal cells store energy by shunting glucose into fat synthesis pathways.
