To help make ideas about energy more concrete, for example, the new unit will use a variety of analogies from more familiar physical systems (e.g., combustion and charging a cellphone battery) to help students understand those same energy - releasing and energy - requiring chemical reactions and energy transfer when they occur in living organisms (e.g., cellular respiration, creating a charge across a membrane in mitochondria and nerve cells) where the reactions are more complex and difficult to observe.

Mitochondria, specialized organelles found in nearly every cell of the body, use cellular respiration to generate one of the most important sources of chemical energy — adenosine triphosphate (ATP), a versatile nucleotide that powers everything from cell division to cell signaling to transportation of large molecules across the cell membrane.
