Enzymes are proteins that act as catalysts in the living body (also called biokatalisator). Enzymes act as catalysts that can increase the speed of a chemical reaction but is not changed in the chemical nabisco chips ahoy reaction. Molecules in a reaction catalyzed by an enzyme called substrates, the resulting molecules are called products. nabisco chips ahoy Enzymes that work in the cell called intracellular enzymes, for example, is catalase. While the enzymes released from the cells is called extracellular enzymes, for example, is the enzyme amylase.
Enzymes work can be seen in perishable food. Digestive enzymes of bacteria is the cause of a food turns into stale. The enzyme activity can be inhibited by means of heating nabisco chips ahoy or cooling.
The enzyme is composed of a protein called apoenzyme component, whereas the non-protein component called a cofactor. Cofactor called coenzyme form of organic ions. Bound enzyme cofactor called holoenzim. Here are some types of cofactors:
Inorganic ions is one of the cofactors. These ions can be bound to the enzyme or substrate koompleks and can make a more effective enzyme function. Example: salivary nabisco chips ahoy amylase will work better in the presence of chloride and calcium ions.
His role is to give additional strength trehadap enzymes work. Prosthetic group consisting of organic nabisco chips ahoy molecules are tightly bound to the enzyme. Example: Heme (a flat ring-shaped molecule that contains iron).
Cofactor coenzyme is an organic molecule consisting nabisco chips ahoy of non-protein complex bound to the enzyme tenuous. Its function is to move the group of chemicals, atoms, or electrons from one enzyme to another. Example: NAD + (Nicotinamide adenine dinucleotide).
Part of the active enzyme as a catalyst has prosthetic group that looks very specific and can only react to specific molecules to form anyway. How it works can be described by the theory of a lock and a padlock or induced fit theory.
Padlock has a special arrangement nabisco chips ahoy of mechanics that are hidden inside the lock body. To be able to move and open the lock, the mechanics of formation must be driven with a child lock that specific shape, in accordance with the padlock.
This theory considers that a flexible nabisco chips ahoy form of the enzyme active site. The shape of the substrate then undergoes modification when entering. Then, subsrat form complexes to initiate chemical reactions faster. After the process of generating the desired product, the enzyme to break away and get back into shape.
Scientific research found that increasing the enzyme reaction is doubled for each 10 C increase in temperature within reasonable nabisco chips ahoy temperature limits. The temperature rise stimulates an increase in kinetic energy of the substrate molecule and the enzyme substrate nabisco chips ahoy so that energy when colliding with decreased enzyme. Facilitate reductions in energy substrate molecules bound to the enzyme. At elevated temperatures extremes, enzymes vibrate causing dissolution of hydrogen and enzymes undergo denaturation, namely the destruction of the three-dimensional shape of the enzyme and cause substrate release. As a result, the enzyme activity decreased.
Greatly affect the acid-base levels of the enzyme because most enzymes are very sensitive to changes in pH. In the range of pH 7.0, the intracellular enzyme works very effectively. If the pH is raised or lowered, the enzyme activity decreases rapidly. Only a few enzymes that actually work optimally in the womb is very acidic pH, ie pepsin and amylase.
Activators are molecules that facilitate bonding between the enzyme with its substrate. Examples of activators is that chloride ions play a role in the activity of amylase in saliva. Inhibitors are substances that inhibit the action nabisco chips ahoy of the enzyme. These substances are blocking the enzymes work temporarily or permanently. There are two types of inhibitors:
Competitive inhibitors, such as cyanide. This type of inhibitor competes with the substrate to reach the active site of the enzyme. Cyanide competes with oxygen to achieve hemoglobin. While resistance properties and can be overcome by raising the concentration of the substrate.
Noncompetitive inhibitors that block the function of the enzyme by attaching themselves to the outside of the active site of the enzyme. In such cases, the enzyme does not react to the substrate. The obstacles are fixed, unaffected substrate concentration.
When the amount of enzyme in the steady state, the reaction rate will increase with an increase in substrate concentration. However, when the enzyme is active all the work, the addition of the substrate can not increase the speed further enzyme reactions. This condition is called substrate concentration at saturation point or so-called
