Enzymes accelerate chemical reactions, they are biological catalysts. They do so by reducing the amount of activation energy required for a reaction to occur. The rate of reaction is faster when the activation energy of a reaction is lower. This process of accelerating a reaction by decreasing its activation energy is called catalysis.
In other words, an enzyme does not alter ALL chemical reactions, just a few select ones. The simplest example would your saliva. The saliva contains many enzymes. One of the enzymes is called amylase, which breaks down the food we eat into simpler units (i.e. starch into simple sugars) , which in turn is further broken down by our digestive system.
When enzymes change shape, the process is referred to as an induced fit. During this process, enzymes essentially undergo physical transformations to bind with other enzymes in chemical reactions. These enzymes fit together with like enzymes to form complete reactions, much like the process of completing a puzzle.
Enzymes increase the speed of reactant particles. To complete any reaction there is a potential barrier i.e. energy, enzyme works as catalyst and lowers the activation energy for a reactant to reach the potential barier easily and fast that's how the enzyme increases the speed of rectenct particles to change in the product.

The rate of an enzyme-catalyzed reaction increases with an increase in the concentration of an enzyme. At low temperatures, an increase in temperature increases the rate of an enzyme-catalyzed reaction. At higher temperatures, the protein is denatured, and the rate of the reaction dramatically decreases.
Enzymes are biological catalysts. Catalysts lower the activation energy for reactions. The lower the activation energy for a reaction, the faster the rate. Thus enzymes speed up reactions by lowering activation energy.
During the course of the reaction, the enzyme (E) binds to the substrate/s (S) and forms a transient enzyme–substrate complex (ES). At the end of the reaction, the product/s are formed, the enzyme remains unchanged, can bind another substrate and can be reused many times.
Enzymes help by putting the substrate(s) in the right position to react. Like all catalysts, enzymes increase the rate of chemical reactions by lowering the reaction's activation energy. Activation energy is the energy needed for the reaction to proceed.
Enzymes speed up chemical reactions by lowering the amount of activation energy needed for the reaction to happen. The reactant(s) of a reaction being catalyzed by an enzyme.
Enzymes allow many chemical reactions to occur within the homeostasis constraints of a living system. Enzymes function as organic catalysts. A catalyst is a chemical involved in, but not changed by, a chemical reaction. Many enzymes function by lowering the activation energy of reactions.
Enzymes are proteins that help speed up metabolism, or the chemical reactions in our bodies. They build some substances and break others down. All living things have enzymes.
If the concentration of the substrate is low, increasing its concentration will increase the rate of the reaction. An increase in the amount of enzyme will increase the rate of the reaction (provided sufficient substrate is present).
Enzymes speed up reactions by lowering activation energy, the lower the activation energy for a reaction, the faster the rate.
Enzymes in our bodies are catalysts that speed up reactions by helping to lower the activation energy needed to start a reaction. Each enzyme molecule has a special place called the active site where another molecule, called the substrate, fits.
Enzymes are catalysts, so they affect activation energy by decreasing the required amount of activation energy allowing chemical reactions to occur or speed up.
Which of the following do enzymes change? ΔG, reaction rate, types of product, activation energy, the laws of thermodynamics. Enzymes increase the reaction rate and decrease the activation energy. Enzymes do not change the other parameters.
