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 variable is one which is observed and not manipulated by a scientist?
An observed variable that is not manipulated by a scientist is known as a dependent variable. It is the outcome or response that researchers measure in an experiment to assess the effect of changes in the independent variable. Since the dependent variable is influenced by the independent variable, it helps in understanding the relationship between the two. However, the scientist does not directly change this variable; they simply observe its behavior in response to manipulations of the independent variable.
What is research mediating variable?
A research mediating variable, also known as a mediator, is a variable that explains the relationship between an independent variable and a dependent variable. It acts as an intermediary, helping to clarify how or why the independent variable influences the dependent variable. By including a mediating variable in a study, researchers can gain a deeper understanding of the underlying mechanisms driving the observed effects. This enhances the overall validity of the research findings.
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?
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 and dependent 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
