Consider two enzyme reaction solutions.Solution 1 has a ratio of enzyme to substrate of 1:100.Solution 2 has a ratio of enzyme to substrate of 100:1.Both solutions contain the same quantity of enzyme.Which reaction gives the greater reaction rate, and why?

Question

Quizplus · Accepted Answer

Enzyme reactions typically follow Michaelis-Menten kinetics, where the reaction rate increases with substrate concentration until the enzyme becomes saturated. In Solution 1, with a higher substrate to enzyme ratio, there is more available substrate for each enzyme molecule, potentially leading to a higher reaction rate until the point of enzyme saturation. In contrast, Solution 2 has an excess of enzyme relative to substrate, which could lead to many enzyme molecules being unoccupied by substrate, thus not contributing to the reaction rate as efficiently.
