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.
1. pH
2. Temperature
3. substrate concentration
3 factors that affect the speed of an enzyme catalysed reaction are:
.Temperature
.Enzyme Concentartion
.Substrate concentration
Concentration of subtrate,Concentration of enzyme,pH,temperature,Inhibitors
the enzyme will change its shape to fit the substrate correctly

The rate of a reactions usually increases when catalyzed by an enzyme. For maximum rate of activity, the enzyme needs optimal conditions.
The function of an enzyme is to increase the rate of a reaction.
There is a direct relationship; as the enzyme concentration increases, the rate of reaction increases.
- with enzymes the rate of reaction is higher- an important characteristic of an enzyme is the specifity
ur face
pH, temperature, substrate concentration and enzyme concentration influences the rate of reaction
* Presence of enzyme * Change in pH * Change in temperature * Change in salt concentration.
Presence of:Competitive inhibitorsNon-competitive inhibitorsAllosteric sitesNegative feedback inhibitionIncrease/decrease of enzyme/substrateCooperativity
is to catalyse or increase the rate of reaction without any change in itself .
When an enzyme is saturated the amount of substrate added no longer as an effect on the rate of the reaction.
the enzyme will change its shape to fit the substrate correctly
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.
