What effect enzymes activity?

Temperature, pH, substrate concentration


What are the four factors that effect enzyme activity?

temperature, pH, concentration of enzymes, and concentration of substrates.


What cause competition?

It slows down or even stop the enzymatic activity because it compete the actove site of the enzymes with substrate and its effect can be reduced by concentrating the concentration of substrate or add more subatrate therefore more substrate are compete with the inibitors


How does changing the substrate concentration exhibit the same effect as changing the enzyme concentration?

For the enzyme to work, its particles must collide with the particles of the substrate. The more particles there are per unit volume, the more frequent the collisions will be. Thus changing the concentration of either chemical will have the same effect.


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.


Is Vmax a threshold of substrate concentration for initiation of an enzymatic reaction?

Oddly phased question in my opinion. Vmax is only effected by the amount of enzyme present in the reaction. Substrate concentration has zero effect on Vmax. There for I believe the answer in no. {Enzyme concentration is responsible for this}


What must be held constant when testing the effect enzyme concentration on enzyme activity?

temperature,pH and substrate concentration


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.


The effect of substrate concentration on the rate of reaction of h202 and catalase?

As the substrate concentration increases, so will the enzyme activity and hence there will be a quick reaction. however, only up to a certain point ( where, if you drew a graph of the reaction, the line will level off ) as all the active sites in the enzyme are occupied and the reaction cannot go any faster. Here more enzymes will be needed to speed up the reaction.


9th grade level biology question. Temperature and what can affect enzyme activity?

effect of ph and concentration of subtrate


How do you change the concentration of the substrate where the substrate is milk and the enzyme is renin?

i just did this experiment in class today. what you need to do is add water to the milk. but you have to keep the same amount of milk in all of them. this is if you are testing the effect of substrate concentration on renin. so you have one experiment with 8ml of milk and then one with 6 ml of milk and 2 ml of water and 4 ml of mik and 4ml of water and so on ... be carefful to stir the solution a bit i hope this helps


What is the use of substrate in Field Effect Transistor?

The use of substrate in Field Effect Transistors is for it to serve as insulating material between the gate and the source.
