Based on Michaelis-Menten enzyme kinetics, the initial rate of reaction, vi, is dependent on maximum rate Vmax, substrate concentration [S], and the enzyme's Michaelis constant Km, which represents the the tendency of the substrate/enzyme complex to dissociate. The dependence on enzyme concentration is factored into the maximum rate. The equation to describe this is: vi = Vmax([S]/(Km+[S])) Follow the link below for details.
Concentration of the enzyme and/or it's substrate.
Temperature of the surroundings.
The pH of the surroundings.
As the substrate concentration increases so does the reaction rate because there is more substrate for the enzyme react with.
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.
The enzyme is liberated free to repeat the action again. That is the beauty of enzymes.
A change in pH can denature an enzyme, meaning the reaction would stop.
Very high activation energy is needed in enzymelss reactions
Any chemical reaction or series of reactions catalysed by an enzyme.
3 factors that affect the speed of an enzyme catalysed reaction are: .Temperature .Enzyme Concentartion .Substrate concentration
Delta G (d)
Generally in an enzyme-catalyzed reaction, the reactant is called the substrate, which in association with the enzyme forms the product.

As the substrate concentration increases so does the reaction rate because there is more substrate for the enzyme react with.
At low substrate concentrations, the rate of enzyme activity is proportional to substrate concentration. The rate eventually reaches a maximum at high substrate concentrations as the active sites become saturated.
Carbonic acid. The reaction is: H2O + CO2 -----> H2CO3 ----> H+ + HCO3- The reaction is catalysed by an enzyme called carbonic anhydrase. After it has formed it separates (dissociates) into hydrogen ions (H+) and hydrogen carbonate ions (HCO3-).
By heating the homogenate. proteins are innactivated by heat and enzyme activity is lost
because the enzyme is becoming denatured

An Enzyme must always be a protein. Any Enzyme is always categorized as the amine in the amino acid sequences that comprise it, and anything made of amino acids is automatically categorized as a protein. Therefore, not all proteins are enzymes, but all enzymes are proteins.
