Enzymes in biomolecule.?please explain.? |
|
Answer» There are also organic or inorganic compounds known as co factors ...without which many enzymes won\'t work. In these cases the protein part of the enzyme is called the apoenzyme. There are also certain inhibitors which are required to stop the function of enzymes when not needed. When these inhibitors closely resemble the substrate. These are called competitive inhibitors. As they compete with the substrate to bind with the enzyme. Most of the Enzymes are proteins. Their function is to catalyse a reaction. A reaction which would take a lot of time and energy to happen ...using an enzyme can take place in seconds. For eg. CO2 \'s reaction with water under normal conditions is very slow.. about 200 molecules of H2co3 an hour. But using Carbonic anhydrase ( an enzyme) you can form 600,000 molecules per second. Enzymes do this due to their structure. In their structure there are crevices ...known as active sites. The reactant or substrate fits in this active site perfectly. After this the bonds of the substrate are loosened so that it can form the product more easily and with less energy requirements. |
