What are the 3 factors that can change the rate of enzyme reaction?

The first factor is Enzyme concentration or subtrate concentration.The rate of enzyme action is directly proportional to to the availability of enzyme provided the substrate concentration unlimited.Or the rate is directly proportional to the substrate concentration if enzymes are limited but if enzyme concentration is kept constant then upto the certain level the increase in substrate amount will no longer increase the rate of enzyme action.
Second factor is temperature.The rate if an enzyme action is always directly proportional to the increase in temperature but upto the specific limit called as optimum temperature.
Third factor is the pH value.Enzymes can work efficiently over a narrow range of pH called as Optimum pH.A minor change in pH value can denature the enzyme.

What happens to the rate of an enzyme controlled reaction when the substrate level is high and remains high?
the enzyme will change its shape to fit the substrate correctly
How does an enzyme work What are the fore factors that affect the emzynes rate of reaction?
isn't the reason for this site iis your suppost to know the answer ??
What is the function of an enzyme?
The function of an enzyme is to increase the rate of a reaction.
What happens when an enzyme catalyzes a reaction?
The rate of a reactions usually increases when catalyzed by an enzyme. For maximum rate of activity, the enzyme needs optimal conditions.
What can Tobin conclude about the relationship between the enzyme concentration and the reaction rate in the presence of excess substrate?
There is a direct relationship; as the enzyme concentration increases, the rate of reaction increases.
What are two factors that are affected when an enzyme is added to a chemical reaction?
- with enzymes the rate of reaction is higher- an important characteristic of an enzyme is the specifity
What things can change the rate of an enzyme catalyzed reaction?
ur face
Is there any Procedure in enzyme and factors that affect enzyme activity?
pH, temperature, substrate concentration and enzyme concentration influences the rate of reaction
What changes the rate of a reaction?
* Presence of enzyme * Change in pH * Change in temperature * Change in salt concentration.
What are three factors that control the rate of enzyme reaction?
Presence of:Competitive inhibitorsNon-competitive inhibitorsAllosteric sitesNegative feedback inhibitionIncrease/decrease of enzyme/substrateCooperativity
What has no effect on the rate of an enzyme-catalyzed reaction?
When an enzyme is saturated the amount of substrate added no longer as an effect on the rate of the reaction.
What is the function of the enzyme catalyse?
is to catalyse or increase the rate of reaction without any change in itself .
What happens to the rate of an enzyme controlled reaction when the substrate level is high and remains high?
the enzyme will change its shape to fit the substrate correctly
How does the non-competitive inhibitor decrease the rate of an enzyme reaction?
Noncompetitive inhibitors decrease the rate of an enzyme reaction by bonding to an enzyme somewhere other than the active site, deforming it and permanently disabling the enzyme, so that enzyme can never function again, so the rate of reaction decreases.
