Question

Enzymes drastically lower the energy barrier for biochemical reactions. The uncatalyzed acid hydrolysis of sucrose requires an activation energy of approximately $6.22	ext{ kJ/mol}$. When this exact reaction is biologically catalyzed by the specific enzyme sucrase, the activation energy drops significantly to $x	ext{ kJ/mol}$. Determine the nearest integer value of $x$.

Prashant Kotian · Accepted Answer

Correct answer: 2. Enzymes operate by providing an alternative reaction pathway with a significantly lower activation energy. While the acid-catalyzed hydrolysis of sucrose requires , the presence of the enzyme sucrase drops the activation energy to just . Rounding to the nearest integer yields .
