Which outcome results when isotopic hydrogen substitutes normal hydrogen in proteins?

💡 Explanation

Substituting deuterium for hydrogen reduces the tunneling rate because the heavier isotope decreases the quantum mechanical transmission probability through barriers via the kinetic isotope effect, therefore reaction rates decrease rather than increase in proteins.
