Analogy
Metabolism is like a living system solving a small survival problem: each part has a job, and the answer depends on how those jobs connect.
Why now: An analogy helps when the definition feels abstract.
Do this: Match each part of the analogy to the science idea.
Learn it
Metabolism is the sum of all chemical reactions in the body.
Reactions build larger molecules and break down molecules to release energy.
The liver plays a key role in metabolism and detoxification.
