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.
What would happen to the rate of a reaction if the concentration of substrate was increased after the point of saturation?
zff
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 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.
Why will increasing the substrate concentration not decrease the effect of a non competitive inhibitor?
Because you will still have the same number of enzymes inhibited. For example, you have 20 enzymes and 10 non-competitive inhibitors. Regardless of substrate concentration, at any one time, there will only be 10 enzymes available to accept a substrate. Increasing the substrate concentration does not affect this.

it is a type of enzyme.

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.
What factors affect the rate of enzyme activity?
-Heat, temperature, &pHtemperature, pH level, concentration of enzyme, concentration of substrate( my sec.1 science book)
Allosteric enzymes are most effective when the substrate concentration is?
d
What effect enzymes activity?
Temperature, pH, substrate concentration
How are enzymes affected by concentration levels?
Higher concentration will mean that there is a higher probability that the substrate will find the enzyme. There will be a point though that you will start seeing dimishing returns as the concentration is sufficient for every enzyme molecule to have a substrate all the time.
