How do enzymes alter the rate of chemical reactions? Enzymes speed up the rate of chemical reaction. Enzymes are biological molecules made of proteins that help speed up the rate of a chemical reaction: either it serves as a catalyst, or it binds with other molecules to produce a new molecule that helps hasten a reaction.
The rate of enzyme reaction is measured by the amount of substrate changed or amount of product formed during a period of time. The rate is determined by measuring the slope of the tangent to the curve in the initial stage of the reaction. The steeper the slope, the greater is the rate.
What is the function of an enzyme?, Enzymes create chemical reactions in the body. They actually speed up the rate of a chemical reaction to help support life. The enzymes in your body help to perform very important tasks. These include building muscle, destroying toxins, and breaking down food particles during digestion.
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 speed the reaction, or allow it to occur at lower energy levels and, once the reaction is complete, they are again available. In other words, they are not used up by the reaction and can be re-used. Enzymes are designed to work most effectively at a specific temperature and pH.
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.
What happens to the products and enzyme after the reaction is complete? The products are released. The enzyme does not change in any way. This allows the enzyme to catalyze another reaction.

So in summary step one is the formation of enzymeMoreSo enzymes can be reused again and again. So in summary step one is the formation of enzyme substrate complex by the binding of substrate to the active site of the enzyme.
Which of the following is changed by the presence of an enzyme in a reaction? The activation energy. (An enzyme lowers the amount of energy required to get the reactants to the transition state.)
Enzymes speed up chemical reactions by lowering the amount of activation energy needed for the reaction to happen.
Find an answer to your question 1) How do enzymes speed up chemical reactions? Enzymes
Answer: enzymes are biological catalysts which speeds of up chemical reactions which is occuring on an organism. Explanation: when an enzyme is deposited to a metabolic reaction, the active site of the enzymes me will be attaching to the substrate particle. then the substrate particle will be broken down to product particles

An enzyme is a Biological catalyst. When the substrate enters the active site of a enzyme it speeds up a reaction. This is helped by the temperature and PH being at optimum (just the right about ...
The standard definition of an enzyme is a protein molecule that functions as a biological catalyst, allowing reactions to occur more quickly than they normally would. The reason enzymes are able ...
Enzymes change shape during the reaction process , which allows them to efficiently reduce activation rates. 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 ...
Enzyme active sites are stabilized by multiple weaker reactions (such as hydrophobic contacts, hydrogen bonds and electrostatic interactions) that ultimately allow them to support rapid chemical reactions .

There are several factors that can increase the rate of a reaction. Raising the temperature can speed a reaction because the molecules have more energy and therefore bump into each other more frequently.
In other words, they are not used up by the reaction and can be re-used. Enzymes are designed to work most effectively at a specific temperature and pH. Outside of this zone, they are less effective. At very high temperatures, enzymes, because they are made of protein, can be denatured or destroyed.
The enzyme, lactase(enzyme names often end in -ase) breaks lactose into its two monosaccharide components.
Outside of this zone, they are less effective. At very high temperatures, enzymes, because they are made of protein, can be denatured or destroyed. The material on which the enzyme will act is called the substrate.
The material on which the enzyme will act is called the substrate. The enzyme attaches to the substrate molecule at a specific location called the active site. When the enzyme has attached to the substrate, the molecule is called the enzyme-substrate complex. For example, the sugar found in milk is called lactose.
Once the activation energyis added, the reaction will continue if the final energy state is lower than the initial energy state. A good example is a lightning strike that starts a forest fire which, once started, will continue to burn until the fuel is used up.
Some reactions can even run in both directions depending on the concentration of molecules. For example, carbonic anhydrase can catalyse the conversion of bicarbonate, a blood pH buffer, into water and carbon dioxide, or can catalyse the reaction in the opposite direction when water and carbon dioxide are more abundant.
