In the digestive system long chains of molecules are broken down into small units by the action of enzymes.
Enzymes is a plural noun, so it can be used like this.
Enzymes are found in saliva.
Enzymes are composed of amino acids, and have different bonds such as a hydrogen bond which maintains the enzyme's shape. Factors such as temperature and pH have an effect upon the enzymes structure. Enzymes have slower rates of reaction when the temperature is below the enzymes optimum temperature. This is due to the fact that hydrogen bonds are stronger at lower temperatures meaning that the enzyme is less flexible and so, using the induced fit theory, this means that the substrate is less able to fit into the enzymes active site meaning less substrate is broken down therefore the rate of reaction is much less than it would be at the enzymes optimum temperature. When the temperature also exceeds the enzymes optimum temperature the rate of reaction is again slower that it would be at the optimum temperature, this is due to the high temperature causing the hydrogen bonds to be broken, meaning the enzyme can be denatured, and there is a point where the enzymes are unable to "renature" (when temp is returned to optimum) because too many hydrogen bonds would have been broken. pH is a factor which also affects the enzymes structure, by changing the pH from the enzymes optimum pH you are then causing there to be a change in the enzymes structure and molecular shape. pH can in turn strengthen or weaken the intermolecular forces like the hydrogen bonds. Competitive inhibitors can also alter the enzymes function. Competitive inhibitors have a molecular shape which is similar to the shape of the substrate; This means that they can occupy the enzymes active site meaning that they compete with the substrate for an available active site. The difference between the concentration of the competitive inhibitor and the substrate determines the effect upon the enzyme activity, if the competitive inhibitors concentration is highest the effect of the substrate is lessened. The inhibitor is not permenantly bound to the enzymes active site, so when it leaves another molecule may take its place, either another inhibitor or substrate. Sooner or later all of the substrate will occupy active sites of enzymes, but if the inhibitor concentration is higher this may take some time. Non-competitive inhibitors can also effect the enzyme activity by attaching themselves to the enzyme, but not at the active site. This attachment means the enzyme's active site may under-go a shape change meaning that the substrate may not fit into it, causing the effect of the enzyme to be lowered as less substrate can be broken down. Non-competitive inhibitors may be permanent. Hope this helps you, even if it is very slightly.
Not all of them are catalytic. There is a class of proteins called enzymes that are catalyzing biochemical reactions. Enzymes are take part in the reaction to speed by the reaction without consuming itself, meaning they can be recycled to the next reactions. Protease, lactase, APOBEC3G are some examples.
Enzymes are substrate specific; meaning that their active site only allows for a certain substrate to bind - in this case, pectin, and the enzyme has no effect on any other biological molecules
DNA can be cut into smaller fragments by enzymes (which are proteins) known as restriction endonucleases (REN's). These enzymes are sequence specific - meaning they produce a cut only at a particular site on the DNA strand. This site where the cut is produced is called the restriction site. Restriction sites are 4 - 6 nucleotides in length. Every restriction enzyme has a different restriction site. This property allows researchers to treat two different DNA samples with the same set of restriction enzymes and then analyze the resulting fragments.A. DNA finger printing
Of course. That is the meaning of ' noncompetitive inhibitor. ' It does not compete with the substrate at the active site but inhibits enzyme activity at the allosteric ( other site ) site.

The professor used a series of diagrams to elucidate the complex scientific concept for the students.
noting or pertaining to a sentence that is easily parsed incorrectly because its beginning suggests it has an interpretation that it clearly does not have.
I have utter contempt for people who plagiarize this sentence without giving me credit.
She wanted to fascinate the crowd and leave them awestruck.

A spicies that spend there time in the kitchin.. LOL
by saying that i have an alter ego
Certainly! Here is a sentence with multiple interpretations: "I saw a man on a hill with a telescope."
