Increasing the concentration of a substrate substance slows down the rate of reaction?
No, if you increase the concentration of a substance there is a more likely chance of particle collisions occurring. Meaning the higher the concentration the faster the rate of reaction.
Imagine people walking around in an empty room, the more people there are in the room, the more likely it is that they will begin to bump into each other, it's the same with particles. The bumping into each other (or collisions) is what will increase the rate of reaction.
Conversely if you lower the concentration, there is a lot less chance that the tiny particles will collide with one another meaning the rate of reaction will decrease.
Hope this Helps!

How does changing the concentration of the limiting substance affect the rate of reaction?
Substrate concentration is directly proportional to rate of reaction because more enzymes are able to act on it but this happen only until all the active sites are covered than reaction rate becomes constant.
What does increasing concentration mean?
Increasing concentration typically refers to adding more of a substance into a solution to make it more potent or dense. This can lead to various effects such as increasing the reaction rate, solubility, or effectiveness of the solution.
What is the relationship between concentration and reaction rate?
In general (but not always), the reaction rate will increase with increasing concentrations. If the reaction is zero order with respect to that substance, then the rate will not change.
What is the relationship between substrate concentration and enzyme activity?
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.
How is the enzyme affected during the catalyzed reaction?
The higher the substrate concentration, the higher the rate of reaction, up till the point when the limiting factor is no longer the concentration of substrate but other factors like enzyme concentration of temperature.
Increasing the substrate concentration in an enzymatic reaction could overcome what?
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.
What does your data indicate about the optimum substrate concentration for this lactase catalyzed reaction?
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.
Why would you expect the rate of an enzyme-catalyzed reaction to increase proportionately to enzyme concentration given an unlimited supply of substrate?
No, since the reaction reaches a max rate depending on the speed of which the Enzyme bonds to the substrate and the speed at which the enzyme catalyzes the reaction to produce enzyme and product (shown below). E + S --> ES (E - enzyme, S - substrate, P - products) ES --> E + P Thus, if each reaction rate is not equal to each other, the rate of the overall reaction is not only proportional to both the concentration of enzyme and substrate.
What happens when increasing the substrate concentration when there is less substrate than enzyme?
Dunno. But this is pretty cool. But if i search the question, i obvioudly don't know it, so why would i be given an optionto answer it?
How could you test to see if an enzyme was completely saturated during an experiment?
To test if an enzyme is completely saturated during an experiment, you can vary the concentration of the substrate while keeping the enzyme concentration constant. If increasing the substrate concentration no longer leads to an increase in the reaction rate, it indicates that the enzyme is saturated. Additionally, you can plot a graph of reaction rate against substrate concentration and observe if it reaches a plateau.
How does changing the concentration of the limiting substance affect the rate of reaction?
Substrate concentration is directly proportional to rate of reaction because more enzymes are able to act on it but this happen only until all the active sites are covered than reaction rate becomes constant.
What is substrate concentration?
Substrate concentration refers to the amount of substrate present in a chemical reaction. It is a key factor that influences the rate of a reaction, as higher substrate concentrations typically lead to an increase in reaction rate until the enzyme becomes saturated.
What happens to the rate of enzyme concentration when you increase substrate concentration?
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.
Describe the relationship between substrate concentration and the initial reaction rate of an enzyme-catalyzed reaction Is this a linear relationship What happens to the initial reaction rate as sub?
As the substrate concentration increases so does the reaction rate because there is more substrate for the enzyme react with.
What does increasing concentration mean?
Increasing concentration typically refers to adding more of a substance into a solution to make it more potent or dense. This can lead to various effects such as increasing the reaction rate, solubility, or effectiveness of the solution.
