Question: The velocity of enzyme-catalyzed reactions roughly increases to how many folds with a 10°C rise in temperature?
Options:
4 times
Doubles
10 times
No change occurs
✅Explanation:
The velocity of enzyme-catalyzed reactions typically doubles with a 10°C rise in temperature within the optimal temperature range for the enzyme. This phenomenon is quantified by the Q₁₀ value, which represents the factor by which the reaction rate increases for a 10°C temperature increase.
Q₁₀ values typically range from 2 to 3 for most biological processes, including enzyme-catalyzed reactions. This means that the reaction rate roughly doubles with each 10°C increase in temperature within the optimal range.
