it is a type of enzyme.
Factors that affect the rate of enzyme activity include temperature, pH, substrate concentration, and enzyme concentration. Temperature and pH can alter the shape of the enzyme, affecting its ability to bind to the substrate. Changes in substrate and enzyme concentration can affect the frequency of enzyme-substrate collisions, which impacts the rate of reaction.
Increasing the substrate concentration in an enzymatic reaction could overcome low reaction rates due to insufficient substrate molecules available for the enzyme to bind to, thereby accelerating the reaction rate. This is known as the substrate concentration effect, where higher substrate concentrations can lead to higher reaction rates until the enzyme becomes saturated.
Concentration of substrate can affect enzyme activity by impacting the rate of enzyme-substrate complex formation. At low substrate concentrations, enzyme activity may be limited by the availability of substrate molecules. However, at high substrate concentrations, enzyme activity may become saturated as all enzyme active sites are occupied.
The substrate concentration required for the maximum reaction rate is typically the saturation point, known as Vmax. This concentration ensures that all enzyme active sites are fully occupied by substrate molecules. The exact substrate amount may vary depending on the enzyme and reaction conditions.
As the substrate concentration increases so does the reaction rate because there is more substrate for the enzyme react with.
At low concentration of substrate , rate of enzyme action is directly proportional to conc. of substrate .
The fraction of enzyme bound to substrate can be calculated using the Michaelis-Menten equation: [ES] / [E]t = [S] / (Km + [S]), where [ES] is the concentration of enzyme-substrate complex, [E]t is the total enzyme concentration, [S] is the substrate concentration, and Km is the Michaelis constant. This equation gives the ratio of the concentration of enzyme bound to substrate to the total enzyme concentration at a given substrate concentration.

A for Plato users
At low substrate concentrations, the rate of enzyme activity is proportional to substrate concentration. The rate eventually reaches a maximum at high substrate concentrations as the active sites become saturated.
The data indicates that the optimum substrate concentration for the lactase-catalyzed reaction is typically at a concentration where the enzyme active sites are mostly saturated with substrate molecules, leading to maximum reaction rate. Beyond this point, increasing substrate concentration may not significantly increase the reaction rate due to enzyme saturation. This optimum concentration ensures efficient enzyme-substrate binding and catalytic activity.
Because you will still have the same number of enzymes inhibited. For example, you have 20 enzymes and 10 non-competitive inhibitors. Regardless of substrate concentration, at any one time, there will only be 10 enzymes available to accept a substrate. Increasing the substrate concentration does not affect this.
To find out how enzyme concentration affects the activity of the enzyme you must:vary the concentration of the enzyme, by preparing different concentrations (keeping the volume of solution the same)keep the temperature, substrate concentration and pH constantmeasure the activity of the enzyme at each concentrationHow the enzyme activity is measured will depend on the specific enzyme involved.You need to have plenty of substrate (excess substrate) so it doesn't run out during the experiment.In this type of experiment, the enzyme activity is the dependent variable, the temperature, pH and substrate concentration are control variables and the enzyme concentration is the independent variable.
The rate of enzyme reaction is increased when the substrate concentration is also increased. However, when it reaches the maximum velocity of reaction, the reaction rate remains constant.
Temperature, pH, substrate concentration
Increasing the substrate concentration in an enzymatic reaction could overcome low reaction rates due to insufficient substrate molecules available for the enzyme to bind to, thereby accelerating the reaction rate. This is known as the substrate concentration effect, where higher substrate concentrations can lead to higher reaction rates until the enzyme becomes saturated.
If the substrate concentration is high, the rate of enzyme-substrate complex formation will increase until all enzyme active sites are saturated, which is known as enzyme saturation. This means that the rate of reaction will no longer increase with further increases in substrate concentration because all enzyme active sites are already in use.
