The speed at which the reaction takes place. Many reactions, especially exergonic reactions, would take place naturally, but too slowly to help living cells carry out the work they need to do. So enzymes lower the activation energy needed to start the reaction and these reactions in the cell are speed-ed up enough for cellular work to be done.
Enzyme or Catalysts
Generally in an enzyme-catalyzed reaction, the reactant is called the substrate, which in association with the enzyme forms the product.
After a biochemical reaction, an enzyme typically remains unchanged and can be reused in other reactions.
You can speed up an enzyme reaction by increasing the temperature, raising the substrate concentration, or maintaining an optimal pH for the enzyme. Additionally, using enzyme cofactors or coenzymes can also enhance the reaction rate.
You could perform a simple enzyme activity assay. Mix the enzyme with its substrate and monitor the reaction rate over time using a spectrophotometer to measure any changes in absorbance or using a colorimetric assay to detect product formation. Compare the reaction kinetics with a control group lacking either the enzyme or the substrate to determine if the enzyme-substrate combination is necessary for the reaction to occur.
There is no difference. An enzyme is a natural catalyst. Catalysts speed up the rate of reaction without being used up itself.
Enzymes speed up chemical reactions by lowering the activation energy required for the reaction to occur, allowing the reaction to happen more quickly. Without an enzyme, reactions may still occur but at a much slower rate due to the higher activation energy barrier.
A nonenzymatic reaction doesn't use an enzyme.
what coenzyme reduce without altering rate of reaction
ENzyme
ENZYME
I think it frees itself from the product and is ready to be reused.
A catalyst speeds up the rate of a chemical reaction by lowering the activation energy needed for the reaction to occur. In the case of an enzyme-catalyzed reaction, the enzyme serves as a biological catalyst, allowing the reaction to occur more efficiently and at lower energy levels than it would without the enzyme.
The change in ∆G would not be affected by doubling the amount of enzyme in the reaction. The ∆G value of a reaction represents the intrinsic energy difference between the products and the reactants, and it is not altered by enzyme concentration.
An enzyme works by providing an alternate pathway for the reaction, and one that has a LOWER activation energy than the original pathway without the enzyme. It thus speeds up the reaction.
co factor helps the factor in reaction and co enzyme helps the enzyme only
enzyme is a kind of protein that catalyzes specific reactions & abzymes are antibodies that target the transition state of an expected reaction.
