How does initial concentration of substrate effect enzyme activity?
At low concentration of substrate , rate of enzyme action is directly proportional to conc. of substrate .
What would be the likely outcome if you increased the concentration of substrate for an enzyme in the presence of a noncompetitive inhibitor?
Increasing the concentration of substrate will not overcome the effect of a noncompetitive inhibitor. The inhibitor binds to the enzyme at a site other than the active site, causing a conformational change that reduces the enzyme's activity. Therefore, increasing the concentration of substrate will not result in a significant increase in enzyme activity.
What are the four factors that effect enzyme activity?
The four factors that affect enzyme activity are temperature, pH, substrate concentration, and the presence of inhibitors or activators. Temperature and pH can alter the enzyme's shape, while substrate concentration determines the rate of reaction. Inhibitors and activators can either decrease or increase enzyme activity, respectively.
What is the effect of starch concentration on amylase activity?
The effect of starch concentration on amylase activity is that increased starch concentration typically enhances enzyme activity up to a certain point. As starch concentration rises, there are more substrate molecules available for amylase to act upon, leading to increased rates of reaction and more glucose production. However, beyond a certain concentration, the enzyme may become saturated, resulting in a plateau in activity where further increases in starch concentration do not significantly affect the rate of reaction. Additionally, factors such as temperature and pH also play a crucial role in enzyme activity.
What is the independent variable between temperature and enzyme activity?
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.
How does initial concentration of substrate effect enzyme activity?

What does the enzyme activity curve reveal about the relationship between enzyme concentration and reaction rate?
The enzyme activity curve shows that as enzyme concentration increases, the reaction rate also increases. However, there is a point where adding more enzyme does not further increase the reaction rate, indicating that there is a limit to the effect of enzyme concentration on reaction rate.

Which variable is the student's experiment described in the Prelab Activity designed to test?
The student's experiment in the Prelab Activity is designed to test the effect of changing the concentration of hydrogen peroxide on the rate of enzyme activity in the enzyme catalase. This involves manipulating the independent variable (concentration of hydrogen peroxide) to observe its impact on the dependent variable (rate of enzyme activity).
9th grade level biology question. Temperature and what can affect enzyme activity?

What are 3 things that can alter enzyme activity?
1. Temperature. 2. P.H level. 3. Enzyme concentration
How do you calculate specific activity of salivary amylase?
Specific activity of salivary amylase can be calculated by dividing the total enzyme activity (in units) by the total protein concentration (in mg). The formula is: Specific activity = Total enzyme activity (units) / Total protein concentration (mg). This calculation gives a measure of the enzyme's activity per unit of protein.
What are factors affecting enzyme activity?
Concentration ( enzyme to substrate ), temperature and pH.
What is the Effect of dilution on enzyme activity?
At a high ion concentration, the ion interfere with the bonds between the side groups of the amino acids making up the enzyme (which is a protein). This causes the enzyme to lose its shape, called denaturation. If the enzyme loses its shape, it can no longer accept and react substrate, so the rate of enzyme activity decreases.
What factors affect the rate of enzyme activity?
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.
