- Q: A biological catalyst or a chemical reaction facilitator is know as a/an?
- A biological catalyst is an enzyme. Here are more details for you. Enzymes – biological catalysts Normally chemical reactions do not proceed spontaneously, but require the help of a catalyst. A catalyst accelerates a chemical reaction without itself being changed. For example, the reaction of hydrogen with oxygen to produce water requires the addition of the metal platinum. These days we encounter the concept of a catalyst most often in connection with technology for cleaning up the exhaust fumes from our automobiles, where platinum and rhodium catalyze the breakdown of polluting nitrogen oxides. Chemical reactions within living cells must also be catalyzed. Biological catalysts are called enzymes. There is, for instance, an enzyme in our saliva which converts starch to a simple sugar, which is used by the cell to produce energy, and another enzyme which degrades the excess lactic acid produced when we overexert ourselves. All green plants contain enzymes which convert carbon dioxide in the air to nutritious carbohydrates such as sugar and starch. Without enzymes life would not be possible! Enzymes are highly selective. Among the thousands of different compounds in a cell, an enzyme can recognize the right molecule (substrate) and transform it into a new product. This property arises from the special three-dimensional structure of each enzyme. One can compare an enzyme and its substrate with a lock and its key. Enzymes are very effective catalysts. A chemical reaction might require several months to reach completion without a catalyst, but only a few seconds with the help of an enzyme. Since the enzyme remains unchanged, one enzyme molecule can catalyze the transformation of millions of substrate molecules. Up until the beginning of the 1980's, all enzymes were thought to be proteins. We now know that proteins do not have a monopoly on biocatalysis. RNA molecules can also function as enzymes.
- Q: Chemical production of iodine and magnesium with water as catalyst!
- In the 250mL three bottles were equipped with spherical condenser and constant pressure dropping funnel, in the condensate tube connected to the anhydrous calcium chloride drying tube. The flask was placed with 1.5 g of magnesium chip and a small tablet of iodine, 10 g of bromobenzene and 30 mL of anhydrous ether were mixed in a constant pressure dropping funnel. First 1/4 of the mixture into the flask, a few minutes later see the magnesium surface of the bubble generated, the solution was slightly cloudy, iodine color began to disappear. If no reaction occurs, use a hot water bath. After the start of the reaction, stir, slowly dropping the remaining bromophene ether solution, dropping the rate to keep the solution was slightly boiling state, after adding, in the water bath to continue reflow 0.5h, magnesium tablets full effect.
- Q: Are biological enzymes harmful to humans?
- A biological enzyme is a biocatalyst that is produced or extracted from a biological organism. The catalyst is a substance that accelerates the chemical reaction and does not change itself in the chemical reaction. In layman's terms, the catalyst is a special substance that catalyzes it. Enzyme as a member of the catalyst family has its own special properties. Each of the biological enzymes will only selectively react to some chemical reactions. A biological enzyme is equivalent to a key that opens a complex compound whose importance is that its unique structure or multidimensional shape matches a part of the group. Once these two parts are combined, the specific chemical bond in the group molecule changes as if the lock was opened. When the reaction is completed, the enzyme is released and repeated with the next group, followed by repeated repeats. Many chemical reactions in the normal temperature conditions, the reaction is very slow so that the whole process is difficult to be perceived.
- Q: Does a catalyst work for both reactants and products?From my understanding, organic catalyst or enzyme does not necessarily work for the product of the reaction because of the shape of the activation site. However I cannot speak for inorganic ones.
- A catalyst works for either the reactants or the product in a given reaction. If it works for the reactants then the activation site on the enzyme, for example, will only fit on the reactants. If a catalyst is added to a reaction in which it catalyzes the back-reaction, or it aids the products, then the reaction will be reversed. i don't think a catalyst could work for both the reactants and products in one reaction because it wouldn't really be a catalyst anymore; it wouldn't make the rxn progress any faster since it would be canceling out itself by aiding both the reactants and the products. I think this is what you are asking, if not please post more details. I hope I didn't confuse you even more!
- Q: What are the characteristics of the catalyst in the chemical reaction?
- In simple terms: the catalyst itself is involved in the reaction, the quality of the reaction before and after the same, the ingredients do not change. The catalyst can change the rate of chemical reaction, increase the rate of reaction called catalyst, slow the inhibitor.
- Q: What are the requirements for the catalyst for the chemical industry?
- Generally find a few, according to the cost and cost of cost, choose cost-effective
- Q: The quality and nature of the catalyst before and after the chemical reaction did not change this sentence wrong? Why did the "middle school student study" say it was wrong?
- The newspaper is wrong and find the teacher's theory. The
- Q: Is palladium predominantly a catalyst in chemistry?
- Palladium in the chemical mainly to do the catalyst; palladium and ruthenium, iridium, silver, gold, copper and other alloy, can improve the palladium resistivity, hardness and strength, used in the manufacture of precision resistors, jewelry and so on.
- Q: CO and NO react under the action of a catalyst to generate chemical formulas for CO2 and N2.
- Landlord's question should not know how to match it, with the loss of electronic with a constant match
- Q: A substance involved in chemical reflection, but reflects the quality of the material before and after the change, you say it is a catalyst?
- Is a catalyst. The catalyst is actually involved in the reaction, (these are multi-step reaction), but in the final time from the reaction out.
