describe the chemical nature of enzymes.?

Answer 1

http://en.wikipedia.org/wiki/Enzyme

Answer 2

Enzymes are nature's catalysts which means they are neither consumed or changed at the end of the reaction when compared to the beginning of the reaction. They act by lowering the energy required to start the reaction. This is done in a myriad of ways.
To convert N2 and H2 to NH3 man has to use massive temperatures and pressures - nature has plants doing this "fixing" of Nitrogen in their cells as a direct result of enzymes.
They are most definitely NOT inhibitors!!

Answer 3

Enzymes are proteins that catalyze (i.e. enhance up) chemical reactions. In those reactions, the molecules on the beginning up of the approach are called substrates, and the enzyme converts them into different molecules, the products. pretty much all strategies in the cellular choose enzymes so as to happen at significant expenditures. using fact that enzymes are fairly selective for his or her substrates and velocity up basically some reactions from between many opportunities, the set of enzymes made in a cellular determines which metabolic pathways happen in that cellular. like various catalysts, enzymes artwork via lowering the activation ability (?G‡) for a reaction, subsequently dramatically accelerating the cost of the reaction. maximum enzyme reaction expenditures are thousands and thousands of circumstances speedier than those of similar uncatalyzed reactions. as with any catalysts, enzymes at the instant are not ate up via the reactions they catalyze, nor do they regulate the equilibrium of those reactions. regardless of the undeniable fact that, enzymes do variety from maximum different catalysts via being plenty greater particular. Enzymes are customary to catalyze approximately 4,000 biochemical reactions.[a million] not all biochemical catalysts are proteins, using fact that some RNA molecules called ribozymes additionally catalyze reactions. Enzyme activity could nicely be laid low with different molecules. Inhibitors are molecules that decrease enzyme activity; activators are molecules that boost activity. Many drugs and poisons are enzyme inhibitors. activity is likewise laid low with temperature, pH, and the concentration of substrate. some enzymes are used commercially, as an occasion, in the synthesis of antibiotics. besides, some enjoyed ones products use enzymes to velocity up biochemical reactions (e.g., enzymes in organic and organic washing powders wreck down protein or fat stains on outfits; enzymes in meat tenderizers wreck down proteins, making the beef greater handy to bite).

Answer 4

Inhibitors that never get used up.
