What is a hypothesis about the effect of substrate concentration on enzyme activity?
What is the effect of the substrate concentration on enzyme activity? As the concentration of the substrate increases, the rate of reaction also increases until it reaches its maximum point where all enzyme molecules are already active due to the solution becomes saturated with the hydrogen peroxide.
How does the concentration of substrate affect the rate of reaction of catalase?
As the concentration of substrate increased there were more substrate molecules to bond with the active site of the catalase enzyme. Because there was this increase in the substrate concentration each time, there was a greater likelihood that the substrate would bind with the active site and carry out the reaction.
How does changing the substrate concentration compare to changing the enzyme concentration?
Substrate concentration: Increasing substrate concentration also increases the rate of reaction to a certain point. Once all of the enzymes have bound, any substrate increase will have no effect on the rate of reaction, as the available enzymes will be saturated and working at their maximum rate.
How does the concentration of a substrate hydrogen peroxide affect the activity of an enzyme catalase )?
This is because there were more molecules of hydrogen peroxide in the higher concentrations, meaning more collisions took place and there was a greater probability of successful collisions. This resulted in more enzyme-substrate complexes formed in the higher concentrations, and less in each decreased concentration.
How does enzyme concentration affect catalase activity quizlet?
We found that the higher the enzyme concentration in the solution, the higher the rate of enzyme activity. As the enzyme concentration decreases, there are fewer enzymes to facilitate chemical reactions.
Why does increasing substrate concentration increase the rate of reaction?
Increasing Substrate Concentration increases the rate of reaction. This is because more substrate molecules will be colliding with enzyme molecules, so more product will be formed.
Would you expect similar results of the substrate concentration?
Would you expect similar results if the substrate concentration were varied in the same manner as the enzyme concentration? No the rgeater the amount of subtrate the greater the amount of bubbling.
What is the relationship between substrate concentration and enzyme activity?
Enzymes will work best if there is plenty of substrate. As the concentration of the substrate increases, so does the rate of enzyme activity. However, the rate of enzyme activity does not increase forever.
How does catalase concentration affect catalase activity?
If the substrate concentration is increased then the rate of a catalase reaction will also increase until it reaches the optimal concentration or saturation point and will remain constant. This is because there will be more substrate molecules in a higher concentration therefore a higher frequency of collisions.
Why did the catalase function level off when different hydrogen peroxide concentrations were tested?
Why did the catalase function level off when different hydrogen peroxide concentrations were tested? At some point, all the catalase in solution was catalyzing reactions, so even if the hydrogen peroxide concentration was increased, the rate of the reaction could not increase any more.
What happens when substrate concentration increases?
