Enzyme decreases activation energy by properly orienting substrate molecules
If your looking for the answer from modern Biology for 2009, then the answer is: The enzyme speeds up metabolic reactions without being permanently changed or destroyed
Enzymes are organic catalysts. Catalysts lower the activation energy for a chemical reaction.
A catalyst lowers the activation energy of a chemical reaction. Many, but not all, enzymes are catalysts.
k man becae i was just looking for this question and yeahh lol i don know it! but guys look up this cool new rapper thuglifer_124 :) follow me on twitter @ambercolessister
Enzymes lower the activation energy so the reaction can take place at a lower activation temperature/energy.
-Im an AP/College Biology student. Trust me on this lol
In chemistry it is called a catalyst. Enzymes decrease the activation energy needed to start a reaction.
It lowers the activation energy.
It lowers the amount of energy needed.
The minimum amount of energy needed for a reaction to take place is called the activation energy.
Adding a catalyst will make the reaction happen faster because the catalyst makes the Activation Energy (the energy required for the reaction to take place) to lower. Meaning more molecules can acquire this lower number of energy. A chemical reaction that involves a catalyst is a special type. A catalyst, in a given chemical reaction, is something that is both an input *and* an output of the reaction equation. What that means, practically, is that a small amount of catalyst is enough to process any amount of the other inputs. (More catalyst means that a given amount will be processed faster.)
2SO2(g) + O2(g) 2SO3(g)-The reverse reaction is favored.
In Chemistry- Chemical synthesisIn Biology- Side effect
Raising the temperature makes chemical reactions faster.
Enzymes lower the activation energy needed to start a chemical reaction.

a catalyst has no effect in chemical reaction. it only increases or decreases the rate of the chemical reaction.
Activation effect is the effect of spontaneous reactions that release energy. When reactants mix and produce a series of chemical potential energies, the outcome of the reaction results into an activation effect due to the reactions.
A catalyst decreases the activation energy of a chemical reaction.
The reaction will not occur unless the activation energy is met.
catalyst decreases the activation energy of a chemical reaction, thereby increasing the effective collisions and hence the rate of the chemical reaction
There is no straight forward relation between enzyme and activation energy because although energy of reaction is fixed and is governed by laws of chemistry but for biochemical reactions concentration of enzyme and conc. of substrate affect rate of reaction and energy, but in general enzymes decrease activation energy of reaction.
In chemistry it is called a catalyst. Enzymes decrease the activation energy needed to start a reaction.
enzyme catalyze the biochemical reactions by lowering their activation energy. An enzyme which take part in such reaction wont be lost or gained any chemical structure and it would be the same after the reaction.
