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 constant
- measure the activity of the enzyme at each concentration
How 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.
What else can I help you with?
A statement of a possible relationship between the independent and dependent variables?
A dependent variable is a variable dependent on the independent variable. A control variable is something you want to try to keep the same. A dependent variable is something you measure. An independent variable is something you change.
What are the differences between independent and dependent variables?
Independent variables are controlled or manipulated by the researcher to determine their effect on the dependent variable. Dependent variables, on the other hand, are the outcome or response that is measured in an experiment. The independent variable causes a change in the dependent variable.
What are the dependent and independent variables in relationship between resistance and current at constant voltage?
dependent variable is current and independent variable is resisitance
What does experimental variable mean?
An experimental variable is the factor being tested or manipulated in a scientific experiment. It is often the independent variable that researchers change to observe its effects on the dependent variable. By controlling the experimental variable, researchers can examine the relationship between different variables and draw conclusions.
What goal of a scientist is to design an experiment that will be able to distinguish the difference between what?
The scientist wants to design an experiment that will demonstrate the effect of the independent variable on the dependent variable. This idea is to show causality between the two.
What is the independent variable between temperature and volume?
pressure
What is the difference between dependent variable and independent variable?
a dependent variable is something that you cannot change but comes out as a result/an independent variable is something that you change in your experiment like the temperature of something or the amount of something
What is the difference between independent variable and depended variable?
a dependent variable is something that you cannot change but comes out as a result/an independent variable is something that you change in your experiment like the temperature of something or the amount of something
What is the difference between depend variable and independent variable?

What is the difference between the independent and dependent variable?
a dependent variable is something that you cannot change but comes out as a result/an independent variable is something that you change in your experiment like the temperature of something or the amount of something
What is the dependent and independent variable between time and temperature?
it depends really especially on the experiment you are doing.
What is the diffrence between dependent variable and independent variable?
the dependent variable changes with the independent variable. the independent variable only changes when changed by the experimenter. Time is usually an independent variable.
What is the independent variable for does wind shield washer fluid freeze?
The question, as presented does not have any independent variable. It is not about the temperature at which the washer fluid freezes, nor is it a comparison between different fluids.
What the differences between the independent variable and dependent variable?
An independent variable is a variable which stands independent and is unaffected by other variables. A dependent variable is a variable which is a response to the independent variable, and is usually the factor that is being tested in an experiment.
Distinguish between an independent variable and a dependent variable?
The independent variable is the value being manipulated or changed, while the dependent variable is the observed result of the independent variable being manipulated. "IF" you change the independent variable, "THEN" what happens to the dependent variable?
What is the difference between the independent variable and the experimental variable?
the independent variable is changed, and the experimental value measure. So you control the independent variable and change it to measure the results
