Almost all reaction in cells are enzymatic controlled, or I would rather not say controlled but 'driven' or 'made possible'.
Enzymatic reaction are controled by e.g. temperature, pH, concentration, ions, activating and inactivating complexes, etc. but not by themselves as substance.

Which is a type of protein that speeds up chemical reactions in living things?
An enzyme is a type of protein that speeds up chemical reactions in living things by lowering the activation energy of said reactions.
Relate the shape of an enzyme to its ability to help in a chemical reaction?
The shape of an enzyme will determine its ability to help in a chemical reaction. These proteins that will break down substance in the body and catalyze chemical reactions.
What type of organisms have enzymes and what is the purpose of enzymes in living things?
All living organisms (bacteria, archaebacteria, protists, plants, fungi and animals) have enzymes. That is, they synthesise enzymes/produce enzymes, which are essential physiological components. An enzyme is a protein that catalyses an essential physiological chemical reaction. The temperatures at which living organisms live are not high enough for essential chemical reactions to occur fast enough to sustain life. Thus an enzyme is required as the first step to speed a reaction on its way. That is what catalyse means: not just supervise, but facilitate. An enzyme is to be imagined as a 3-D folded protein, which has a slot called an active site into which a compound or macromolecule can temporarily fit. Within the active site, the forces between the constituent chemical groups of the enzyme and its active-site-fitted molecule (substrate) alter the shape of the active-site-fitting molecule in such a way as to facilitate a reaction of that molecule (which can either be the break down of that molecule or the addition of another molecule to that molecule). Once the reaction has been catalysed, enzyme and products of the reaction detach from one another. Almost all reactions are catalysed by enzymes. These reactions can build molecules up (anabolic reactions) or break them down (catabolic reactions). For example, the enzyme amylase breaks down starch into maltose. The enzyme maltase breaks down maltose (a sugar) into a simpler sugar called glucose. The enzyme phosphofructokinase adds a phosphate to a molecule called fructose 6-phosphate which produces fructose 1,6 - bisphosphate, a reaction of glycolysis which is the first stage of cellular respiration. In the Krebs Cycle, also part of cellular respiration, citrate synthetase combines a molecule called oxaloacetate with acetyl-Coenzyme A, which produces citrate. ATP synthase produces ATP, the essential energy-carrying molecule, from ADP. Indeed there are thousands of different enzymes for the thousands of different reactions in a cell! Enzymes are thoroughly essential to all life. All enzymes end in ASE!
Is an enzyme consumed in a reaction?
No. There is no type of a catalyst that is consumed in a reaction.
3 variables that can cause an enzyme to lose its ability to function?
An enzyme is a catalyst for chemical reactions. Three variables that can cause an enzyme to lose its ability to function are temperature, pH level and concentration.
What is an enzymatic process?
Any chemical reaction or series of reactions catalysed by an enzyme.
What ia an enzyme?
an enzyme is protien that catalyzes chemical reactions for organisms
What terms refers to a protein that catalyzes chemical reactions in organisms?
Yes, that is correct.
Does a protein catalyst that speeds up chemical reactions in organisms called an enzyme?
Yes, proteins which catalyze chemical reactions are called enzymes.
Chemical reactions occur on the active on an enzyme?
Enzymes speed up chemical reactions inside living organisms. They are made up of proteins.
Which terms refer to a protein that catalyzes chemical reactions in organisms?
The name is enzyme.
Why above a certain temperature enzyme-catalysed reactions actually go more slowly if the temperature is raised?
because the enzyme is becoming denatured
How temperature affects the enzyme catalysed biochemical reactions?
woah. English please! too many words take in and understand!

Materials that slows down chemical reactions?
In biological chemical reactions, examples of these are called enzyme inhibitors. Enzymes speed up reactions, but enzyme inhibitors slow them down. This can be by either competing with the reactants for a spot on the enzyme, or by altering the enzyme's structure so that it does not speed up reactions anymore. In either case, enzyme inhibitors slow down chemical reactions.
What is important about enzyme catalysis in living organisms?
Enzymes are very important because they speed up the chemical reactions that are required for life.
What is a protein that changes the rate of chemical reactions?
its called an enzyme
