Solution
Correct Answer:
Biological catalysts (proteins)
Enzymes are biochemical catalysts that significantly increase the rate of chemical reactions within living organisms without being consumed.
- Almost all enzymes are Globular Proteins (though some catalytic RNA molecules, called ribozymes, exist).
- They are highly specific in their action, working at body temperature and optimal pH.
- They function by providing an alternative pathway with a much lower activation energy.
This easy difficulty chemistry question is from the chapter biomolecules, covering the topic of enzymes. It appeared in the 2025 exam.
