Concept:As temperature increases, molecular collisions increase, speeding up the reaction rate—but only up to a specific threshold before the protein denatures.
Solution:- The precise temperature at which an enzyme works at its absolute maximum efficiency is called its optimum temperature.
- For most enzymes in the human body, this temperature is around \( 37^{\circ}\text{C} \) (normal body temperature).
- Beyond this point, the intense thermal kinetic energy breaks the delicate hydrogen bonds maintaining the enzyme's 3D shape, leading to rapid denaturation.
Why other options are incorrect:'Fixed', 'Active', and 'Controlled' temperatures are not the standard scientific terms used in biochemistry to describe the peak of an enzyme's activity curve.
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.
