The answer to this question would be: enzyme
<span>Enzyme is a kind of catalyst that </span>will take part in the chemical reaction but it won't be reacted. E<span>nzyme </span>only helps by reducing the energy needed to start the reaction.
Theoretically, the enzyme is not mandatory needed but if you have an enzyme the reaction will be easier, thus increasing reaction speed. But in most case, the reaction might be too slow without enzyme, making enzyme vital in living organism.
I believe that would be oil and vinegar.

Answer:
Time = 4.2273 seconds
Explanation:
The amount of the energy emitted by the microwave = 1100 J/s
It means that :
1100 J of the energy is emitted in 1 second
Also,
1 J of the energy is emitted in [tex]\frac {1}{1100}[tex] second
To calculate:
Time for emitting 4650 J of energy
Thus,
4650 J of the energy is emitted in [tex]\frac {1}{1100}\times 4650[tex] second
<u>Time = 4.2273 seconds</u>
