Metabolism and Bioenergetics
Captions available
The idea
A cell's metabolism is the sum of every chemical reaction taking place inside it; bioenergetics is the study of how energy flows through those reactions.
In practice
Breaking down a sugar molecule and building a new protein are both metabolic reactions, one releasing energy and one requiring it.
Where people slip
Metabolism names every reaction in the cell together, not any single reaction or pathway alone.
