factors influencing enzyme activity

Enzymes - Enzymes are the biocatalysts of life. They are defined as biocatalysts synthesized by living cells. They are simple or conjugate protein and specific in action. At present about 300 enzymes are recognized and classified into six classes by International Union..

Enzyme Catalysis - Enzymes are macromolecules, usually proteins, produced in living systems, which act as catalysts in physiological reactions. The striking characteristics of enzymes are their catalytic power and specificity. Enzymes have immense catalytic p..

The inter-ionic attraction It is the intersection between the ions of the solute at low concentrations. It is not much at low concentrations the inter-ionic cone is very less, but at high concentrations it is appreciabl..

Low ionisation energy Ionisation energy is the amount of energy, which is required to remove the most loosely bound electron(s) from an isolated gaseous atom to form a positive ion. In forming an ionic bond, one atom must form a cation by losing one or more electrons. In general, eleme..

Enzymes in general exhibit the following properties Enzymes are basically proteins. They are globular proteins with a very huge molecular weight. For example, the molecular weight of pyruvic dehydrogenase is 4,600,000! Enzymes can only accelerate a chemical reaction. h..

Enzymes control several metabolic pathways and are highly specific in their action. Enzymes like invertase, zymase and maltase are used in manufacture of alcoholic drinks. Some enzymes are used as therapeutic agents. For e.g., streptokinase is used to dissolve ..

. Pressure depends on two factors namely, force applied and area over which force act..

Temperature is one of the essential and changeable environmental factors. It penetrates into every region of the biosphere and profoundly influences all forms of life by increasing or decreasing some of the vital activities of the organism. It is frequently a limiting ..

This technique is of gaining importance in analytical chemistry. In this technique, the sample containing very small amount of the stable isotope of the element to be investigated is bombarded with neutrons. This element is activated into its radioactive isotope. The radioactivity of thi..

>By negative charges of organic acids when they lose H + ions Thus all these factors lead to the opening of stomata. The stomata closure is due to excretion of K + ions from guard cells surrounding epidermal and subsidiary cells. The stomatal closure is considered to be brought about by a..
