Analogy
Enzymes 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
Enzymes have an optimum temperature and pH.
High temperatures denature enzymes by changing the active site.
Substrate concentration can limit reaction rate.
