Enzymes are not at all consumed or eaten up by the chemical reactions which are taking place within it but at the same time the equilibrium is maintained during the whole activity which is a definitive plus point on the part of these very enzymes.... Enzymes are specific because their activity can easily affect the other molecules which are present and so in return can leave a lasting impression on the whole chemical reaction that is taking place.... On the same token, inhibitors are those molecules which decrease the activity that is going on within the enzymes....

Most of the physiological processes that take place in the body are initiated at the cellular level, at the same time; the cell operation is linked with the enzymes activity.... The replication of the DNA is enzyme catalyzed and the process continues to the transcription of the DNA to RNA (Ribonucleic Acid) which then gives the amino acid and is finally translated to proteins that manifests themselves phenotypically (Alberts 102).... It is the responsibility of the cell to determine what enzyme is required in the body depending on the type of substrate that is present in the body....

However beyond the optimum temperature the enzyme activity decreases.... A change in the structure of the enzyme may affect the enzymes binding ability and consequently its activity.... If catecholase activity is minimally affected at different temperatures and pH then it can be hypothesized that it has a large range of optimal activity.... The aim of this experiment was to test the effect of temperature and pH on the enzymatic activity of catecholase....

The activity of protein also varied between the fractions, with the liver particulate and lysed liver particulate showing higher levels of protein than the supernatant.... Determining what enzymes are present in different cellular components and their level of activity can be achieved through the use of cell fractionation techniques (Scnaitman and Greenawalt, 1968).... As well as variation in function and enzyme composition across organs and areas of the body, this also occurs within organelles present within cells....

Attempts to reduce background LDH activity by minimizing the amount of serum in the media by using 1% FBS, mainly used for maintenance of culture cells without affecting cell survival or promoting growth, resulted in high toxicity of the cells.... Some of the biomarkers developed include enzymes such as lactate dehydrogenase (LDH), an important glycolytic enzyme found in all tissues with high concentrations in the heart and liver.... This enzyme has been widely used in clinical chemistry and toxicology to diagnose cell, tissue and organ damage (Kaplan and Pesce, 1996)....
