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.

Is an enzyme consumed in a reaction?
No. There is no type of a catalyst that is consumed in a reaction.
How do enzymes function speeding up in a chemical reaction?
Enzymes lower the activation energy of a chemical reaction. Since more molecules have sufficient energy to react, the reaction occurs faster.
What happens to an enzyme after it catalyzes a chemical reaction?
Enzymes are not used up in a chemical reaction. Usually, the enzyme will "reset" and be ready to use in another reaction. This is due to the fact that enzymes are proteins, and their shape is what they use in a chemical reaction. Initially, the enzyme has a particular shape. Something happens to the enzyme (usually a shape change, called a conformation change, brought on by the presence of two or more chemical reactants), and the enzyme catalyzes the reaction. After the reaction is catalyzed, the product is released, and the enzyme can "relax." This means it goes back to its normal shape, ready to do it all over again.
Do Enzymes increase or decrease the Activation Energy of a Chemical Reaction?
decrease
Do enzymes change shape after a reaction occurs?
While the structure of an enzyme can, and often does, change over the course of a reaction, after a reaction has completed, enzymes are returned to their starting state. It is worth noting that certain cofactors (such as ATP or GTP) may also need to be replaced in order for the reaction to procede again.
Is an enzyme consumed in a reaction?
No. There is no type of a catalyst that is consumed in a reaction.
What is a true of a substrate?
It acts as a reactant. In a chemical reaction A substrate is a molecule that is reacted on by enzymes.
In a bio-chemical reaction what are the bio-molecules which are not consumed yet their presence is required?
In every biochemical reaction in the body, a specific enzyme is required to catalyze (speed up) the reaction. These enzymes are required for the reaction to take place, but are not consumed themselves in the reaction.
Is it true that Enzymes are not consumed during a chemical reaction?
Correct. Enzymes help to speed up chemical reactions. They may speed them up, costing them some energy, but they are never used up.
Are enzymes affected by the chemical reaction they speed up?
Enzymes are biological catalysts. A catalyst speeds up a reaction by lowering the activation energy required. In other words a catalyst offers an alternative pathway to increase the rate of reaction- it is not consumed during a reaction, or affected.
What aspect of chemical reaction is affected by enzymes?
The reaction rate is affected by enzymes.
Are enzymes consumed after chemical reactions?
yes indeed
Which statement best explains how enzymes speed up chemical reactions?
Enzymes lower the activation energy of a chemical reaction.
IS it true that enzymes increase the number of collisions in a chemical reaction?
No that is false. Enzymes do NOT increase number of collisions in a chemical reaction.
What do enzymes change about a chemical reaction?
The Reaction Rate
How do enzymes speed up chemical reactions?
Enzymes lower the activation energy of a chemical reaction.
How are enzymes represented in a chemical equation?
Enzymes are catalysts and increase the speed of a chemical reaction without themselves .A chemical reaction can be represented by a chemical equation. An enzyme is a protein that speeds up a biochemical reaction .
