Concept:For molecules to react, they must collide with enough force to disrupt existing electron clouds and reach an unstable transition state.
Solution:- The minimum amount of energy required to achieve this transition state is the activation energy.
- Enzymes act as physical templates, binding substrates in the perfect orientation and putting stress on their bonds.
- This incredibly efficient process severely lowers the activation energy required, allowing the reaction to proceed rapidly at physiological temperatures.
Why other options are incorrect:Enzymes do not reduce the innate kinetic or potential energy of the molecules, nor do they cool the reaction down (heat energy). They exclusively target the energy barrier of the transition state.
Quality & Fidelity Assurance:
Every question on BeambePrep is rigorously curated against the official PMDC syllabus with zero filler, zero out-of-syllabus content, and zero typos. When an authentic past paper originally contained a historical mistake or ambiguity from the examining board (such as UHS or NUMS), BeambePrep faithfully reflects the original paper while detailing the nuance and scientific consensus in the autopsy above.
