What is the effect of changing the substrate concentration on the catalytic activity of enzymes? To answer this question, students can design an experiment to measure how the reaction rate changes as they gradually increase the substrate concentration while keeping other factors constant. They can then plot their data and determine the kinetic parameters of the enzyme, such as the Michaelis-Menten constant (Km) and maximum reaction velocity (Vmax), which can reveal important information about the enzyme's efficiency and specificity.
