What effect does substrate and enzyme joining have on chemical bonding?
enzyme catalyze the biochemical reactions by lowering their activation energy. An enzyme which take part in such reaction wont be lost or gained any chemical structure and it would be the same after the reaction.
Can an enzyme make an endothermic reaction exothermic?
False. Not necessarily. Do not confuse kinetics with thermodynamics. Although an enzyme as a catalyst decreases the activation energy of the reaction, this says nothing about whether the reaction is ultimately endothermic or exothermic.
Is the active side of an enzyme highly changeable portion of an enzyme that adapts to fit the substrates of various reactions?
When an enzyme binds to the appropriate substrate, subtle changes in the active site occur. This alteration of the active site is known as an induced fit.Induced fit enhances catalysis, as the enzyme converts substrate to product.Release of the products restores the enzyme to its original form. The enzyme can repeat this reaction over and over, as long as substrate molecules are present.
Why does the concentration of the enzyme make a difference to how fast the reaction works?
The concentration of the enzyme affects the rate of reaction because enzymes are catalysts that speed up chemical reactions by increasing the frequency of successful collisions between substrates. Higher enzyme concentrations mean more enzymes are available to convert substrate molecules, leading to a faster overall reaction rate. Once all substrate molecules are bound to enzymes, further increases in enzyme concentration will not speed up the reaction.
What is the purpose of the active site of an enzyme?
The active site is the part of an enzyme where the breaking down of a substance (catabolysm) or the putting back together of a substance (anabolysm) occurs. Catabolysm and anabolysm make up your metabolism.

How do enzyme in your body make chemical reactions occur at safe temperatures?

What is an enzyme and how does it help speed up a chemical reaction?
enzymes provide an alternative pathway for the reaction,one which is lower than the original activation energy. according to the Maxwell distribution,the number of molecules having the new activation energy is greater,thus there are more molecules which can react and therefore rate of reaction is greater,thus causing enzymes to be catalysts.
How does enzyme concentration affects the rate of enzyme action?
it slows down the reaction time of the enzyme because there are too many substrates bumping into each other and make it harder for them to bind to the enzymes.
What happens to bonds during the enzyme substrate complex?
Depends on which enzyme and which substrate, but it goes like this with any of them. Let's take amylum (starch, the substrate) and amylase (saliva, the enzyme). A enzyme binds itself to a substrate, and forms a enzyme substrate complex. The catalyzing powers of the enzyme makes the vulnerable connections in the amylum weak to make it break, which creates product(s) out of the amylum.
Use catalyst in a sentence?
A catalyst is a substance that causes or aids in any type of reaction. Here are some sentences.That enzyme words as a catalyst in your body.She was the catalyst that started the argument.A catalyst is needed to make this chemical reaction occur.
What does a enzyme do in chemical reaction?
An enzyme generally lowers the activation energy necessary for a reaction to proceed. This in turn may cause more of the reactants to go to products.
What happens to an enzyme after it catalyzes a chemical reaction?
Enzymes are not used up in a chemical reaction. Usually, the enzyme will "reset" and be ready to use in another reaction. This is due to the fact that enzymes are proteins, and their shape is what they use in a chemical reaction. Initially, the enzyme has a particular shape. Something happens to the enzyme (usually a shape change, called a conformation change, brought on by the presence of two or more chemical reactants), and the enzyme catalyzes the reaction. After the reaction is catalyzed, the product is released, and the enzyme can "relax." This means it goes back to its normal shape, ready to do it all over again.
Why does Enzyme reaction rate decrease at 37 degrees?
Enzymes are catalysts for chemical reactions. All chemical reactions are affected by temperature. Higher temperatures make the reactions happen faster, and colder temperatures make them happen slower. At 37 degrees, just a little above freezing, many biological enzymes practically stop working.
How does pH affect enzyme functions?
Enzymes lower the amount of Activation Energy needed for a chemical reaction, therefore speeding up the chemical reaction. For an enzyme to do this it needs to be at the correct pH, salinity, and temperature otherwise the enzyme will not be able to work. When an enzyme is in a pH that is not suitable, the enzyme's shape and structure alter and make it unable to speed up a reaction.
Is the active side of an enzyme highly changeable portion of an enzyme that adapts to fit the substrates of various reactions?
When an enzyme binds to the appropriate substrate, subtle changes in the active site occur. This alteration of the active site is known as an induced fit.Induced fit enhances catalysis, as the enzyme converts substrate to product.Release of the products restores the enzyme to its original form.
