Concept:Biological systems maintain homeostasis and rapid metabolism at low body temperatures by using highly specific biological catalysts.
Formula:$$N/A$$
Solution:- Without catalysis, biochemical reactions in the human body would occur far too slowly to sustain life at 37°C.
- To overcome activation energy barriers, enzymes are utilized.
- Enzymes are highly specific; thus, for virtually every discrete metabolic reaction in the body, there exists a specific enzyme to catalyze it.
Why other options are incorrect:While all enzymes are proteins (and thus made of amino acids), saying "protein" is too broad, as many proteins (like keratin) do not catalyze reactions. Vitamins act as coenzymes, but not every reaction requires a vitamin coenzyme.
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.
