Some different things that could speed/slow up/down a chemical reaction are:
Temperature
(If higher, molecules move faster, reactions speeds up) SPEED UP
Temperature
(If lower, molecules will move slower, reaction slower) SLOW DOWN
CATALYST
(A catalyst is anything that SPEEDS up a reaction without being consumed[running out of energy]) SPEED UP
Concentration
More substrates [reactants/puzzle pieces to enzymes faster reaction)SPEED UP
Concentration
(Less substrates- slower reaction) SLOW DOWN
...well, there you go... :)
A catalyst affects the speed of a chemical reaction. If the chemical reaction gives off heat, the reaction may affect the temperature, but the catalyst by itself doesn't affect the temperature.
In living things, catalysts help increase the rate of chemical reactions without being consumed in the process. They lower the activation energy needed for the reaction to occur, making it more efficient. This allows living organisms to maintain the reactions necessary for life at the appropriate speed.
The chemical equation is the word expression of a chemical reaction.The rate of reaction give information about the speed of this reaction.
A catalyst. Definition from Pretence Hall Biology: A catalyst is a protein that speeds up the rate of a chemical reaction.
Speed up the rate of a chemical reaction
A catalyst affects the speed of a chemical reaction. If the chemical reaction gives off heat, the reaction may affect the temperature, but the catalyst by itself doesn't affect the temperature.
enzymes are never consumed in a chemical reaction, therefore the answer to your question is that enzymes that affect the speed of a chemical reaction without being consumed are indeed called enzymes.
Enzymes act as catalysts. They speed up the reaction time.
You can add a catalyst, or raise the temperature, or change the pressure, these are some of the things done to speed up a chemical reaction.

to speed up a chemical reaction
Heat would speed up the reaction, while cold would slow the reaction.
Activation energy is lowered to speed up a chemical reaction.
Enzyme
Enzymes affect the speed of reactions predominantly. In some instances in which more than one reaction is possible, enzymes increase the speed of the normally slower reaction enough to make it predominate, while the other possible reaction is effectively suppressed.
The speed of a given chemical reaction is directly responsible for spontaneity of the reaction. The reaction force and effect is contingent upon the speed of the reaction. The faster the reaction, the more force will be produced.
