- Q:Brief introduction of enzyme as biocatalyst and general chemical catalyst and its personality
- enzyme inactivation (4) enzyme activity can be timely and effective regulation (5) the role of the enzyme conditions are more moderate (6) most of the enzyme (1) the catalytic efficiency is very high (2) Of the catalytic activity is often associated with coenzymes, auxiliary or metal ions, and some enzyme activity also need RNA as a cofactor Caixing, such as telomerase
- Q:Why would the Eact decrease if a catalyst is added?
- A catalyst by its very nature increases the rate of reaction by binding to a reactant, hence changing its shape and reactivity with other reactants. However, the catalyst is neither consumed nor will it change the chemical shape of the products.
- Q:Are biological enzymes harmful to humans?
- Recently, people are increasingly interested in the use of enzymes in cosmetics, not only from a technical point of view, but also from the market prospects and consumer awareness of these seemingly effective raw materials. Enzymes have been used in laundry detergent for more than 20 years and are linked to long-term performance with the ability to provide and enhance strong stain removal capabilities. According to some speculation, their positive response in the market may be interpreted as satisfying the aging population, the pursuit of younger needs to enhance the performance of cosmetics. The natural shedding process of the skin is controlled by the enzymatic reaction, and the specific enzyme dissolves the cell desmosomes that release the dead epidermal cells. These enzymes are produced in dead keratinocytes. Their active sites are phagocytosed with mercapto groups, and cleavage of peptide bonds in a manner similar to that of thio-glycolic acid and mercaptoalanine (plus derivatives) when the hair is broken. Use these types of enzymes and it
- Q:What is a catalyst?
- The catalyst itself reduces the energy barrier (Ea, activation energy) of the chemical reaction, making the reaction easier.
- Q:The last question asked no one answered this question.
- First of all now the most common way to change the ligand.
- Q:i keep messing up on those 2 simple things haha i would apprecaite some help.
- A catalyst is a substance that affects the rate of a reaction. It may participate, but cannot be consumed in the reaction. For example, KMnO4 catalyzes the breakdown of H2O2 into H2O and O2. In the end, as much KMnO4 exists as did in the beginning. An enzyme is a biochemical reagent that allows an organism to convert a compound into other compounds. This is part of metabolic processes. For example, maltose (a sugar composed of a chain of two glucose molecules) can be broken down into glucose by the maltase enzyme. Unlike a catalyst, enzymes may or may not be consumed/altered in the metabolic processes.
- Q:What are the chemical reaction conditions in organic chemistry are catalyst and heating, please elaborate
- This really does not have omnipotent law, their own more than one point, you can classify to remember, when I was in high school is in accordance with the notes, such as poly, polycondensation and the like. In general, the double triple bond addition, plus halogen is not the conditions, plus HCl, HBr and the like to heat; dehydration reaction generally concentrated H2SO4 heating, dehydration condensation is also; there are some special, such as ethylene added to ethanol Special temperature requirements, it seems that 120 degrees, there are other; other addition poly, polycondensation some need catalyst. The The In short, the conditions are many, in general, you do not go to the high school to do more questions after the feeling, encounter problems do not panic general experience can come out according to experience, this also depends on the usual accumulation, if the equation conditions Wrong to deduct points, it is not worthwhile. There are some questions when the examination will give you some information, whether you know do not know should see clearly, although some of the reaction but the subject to the conditions are not the same, when you do according to the title to write conditions, this will not wrong. In addition, thank you for your help, I do not seem to know you
- Q:Explain how a catalyst may increase the rate of chemical reaction?
- Catalysts lower the activation energy (that is, the energy needed for a reaction to proceed) in either the final product or the intermediates. It can do this in a number of ways, including conformational (shape) changes in the intermediates (such as in complex organic molecules), changing the intermediates that form (alternate reaction pathway) or by changing the reactant in a certain way (like sulfuric acid stripping a proton off of a molecule so that nitric acid can bind to it and nitrate it, which would otherwise be energetically unfavorable). In English, catalysts change the molecules so it doesn't take as much energy for the reaction to take place. Think of jumping a hurdle: the same height on either side of it (reactant and product), but if you lower the hurdle (reduce the activation energy) it's easier to get to the other side.
- Q:The chemical equation of heating reaction of benzene and hydrogen under the action of catalyst
- C6H6 benzene + 3H2 - (arrow) C6H12 cyclohexane (Ni catalytic heating)
