An enzyme has its specificity due to________________?
Correct answer: B. Structure
- A. Substrate
- B. Structure
- C. Temperature
- D. Pressure
Explanation
Enzyme specificity arises from the particular three-dimensional structure of its active site, whose shape and chemical groups fit certain substrates. Temperature and pressure can affect enzyme activity but do not determine substrate specificity. Students often choose a because the substrate is involved in the enzyme-substrate complex, but specificity is primarily a property of the enzyme's structure.

About Enzymes as Biocatalysts
Enzymes are protein or RNA biocatalysts that lower activation energy without being consumed, and their active sites bind specific substrates. The topic covers the lock and key and induced fit models, effects of temperature, pH and substrate concentration, cofactors, enzyme specificity, and competitive versus non-competitive inhibition.
