Usually enzymes have the role to catalyse a reaction. That means they aren't changed at all, but they influence the mechanism to reduce the activation energy (the energy needed for the reaction). The reaction is therefore performed more easily.
To put it very simply: It speeds up a chemical reaction.
Enzymes are shaped proteins, normally produced by organisms to catalyse chemical reactions. They function in a similar way to chemical catalysts, by lowering (or occasionally raising) the 'activation energy' for a specific reaction, and are not used as a reactant. oweing to the nature of enzymes, as proteins, they function optimally at a set temperature and pH, as their presence outside these conditions is often to the detriment of the protein structure, or instead, in the case of low temperatures, slows the reaction and frequently fails to meet the activation energy. Enzymes will usually speed up a chemical reaction, and will additionally facilitate it when it would otherwise not occur.
enzymes are biological catalysts that speed up the rate of reaction without being changed or used up
Enzymes act as catalysts in biochemical reactions.
Enzymes speed up a reaction by allowing the reaction to take place at lower temperatures.
It acts as a catalyst, speeding up a slower reaction or allowing a previously impossible reaction to occur.
An enzyme is basically a biological catalyst and will speed up a reaction
The reaction speeds up.

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.
At excessive temperatures, enzymes usually denature or break down into other molecules, thus failing to preform their specific function.Other than that, heat does not affect enzymes much but it does increase the speed of the reaction.
Enzymes lower the activation energy of a chemical reaction. Since more molecules have sufficient energy to react, the reaction occurs faster.
Enzymes lower the activation energy (or free energy of activation for the very scientific) of the chemical reactions they catalyse. The enzymes can make a reaction proceed much more quickly than it otherwise would by astronomical figures, e.g. 109 times! Enzymes don't affect the equilibrium position, but they do affect the rate.
The enzymes in the cell act as catalysts for chemical reactions. They lower the activation energy of these reactions in order to speed up the reaction rate.
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 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.
At excessive temperatures, enzymes usually denature or break down into other molecules, thus failing to preform their specific function.Other than that, heat does not affect enzymes much but it does increase the speed of the reaction.
Enzymes fasten chemical reactions, inhibitors blocks the enzymes and they will not accelerate the reaction.
The reaction rate is affected by enzymes.
They lower the activation energy needed to start a chemical reaction.
Enzymes lower the activation energy of a chemical reaction.
No that is false. Enzymes do NOT increase number of collisions in a chemical reaction.
The Reaction Rate
Enzymes speed up a reaction but they are not changed by the reaction. They are a protein molecule that helps other organic molecules enter into chemical reactions with one another but is itself unaffected by these reactions. In other words, enzymes act as catalysts for organic biochemical reactions.
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 .
Heat generally speeds up the reaction, while cold will slow it down. The enzymes in the cold are frozen.
