What is the substrate of the enzyme pepsin? What are the products of this enzymatic reaction? Give an example of an enzyme found in a living organism. Describe the reaction it catalyzes and what is going on molecularly at the active site of that enzyme to allow i...
In general, enzyme activity can be considered to be the rate at which an enzyme catalyzes a reaction. Experiments that determine enzyme activity are called enzyme assays. Several factors affect enzyme activity including substrate concentration, enzyme concentration, temperature, and pH. Each enzyme is...
PCR is a Polymerase Chain Reaction. Kary Mullis developed it in 1983. It is a technique used to amplify a specific segment of DNA. The technique mainly involves three steps: denaturation, annealing, and elongation. This technique is commonly used in molecular biolo...
Substrate in Chemistry - A substrate is also a substance which an enzyme, substance produced by living cells acts on to produce a chemical reaction. As far as chemistry is concerned, a substrate is generally seen as a chemical material that some other ma
Chemists usually quantify the effect that a parameter has in the rate of a reaction with the order. The IUPAC defines that a reaction is of order α with respect to a substrate A only when the macroscopic rate can be expressed by a power law: r = k[A]α[B]β… [1]. For re...
A. Respiratory substrate in germinating wheat grains is carbohydrate. When carbohydrates are completely oxidised, the RQ is equal to unity. B. Zymase is a complex mixture of many enzymes which requires several coenzymes for its action. The enzyme complex-zymase catalyses series of reaction taking...
It has been proposed that the mechanism follows a -type catalytic cycle; however, our calculations find an alternative low energy pathway whereby the bound substrate has two important functions in the catalytic cycle, namely first as a proton donor and later as the substrate in the reaction ...
Pyrophosphoric acid sequencing technology is an enzyme cascade chemiluminescence reaction in the same reaction system catalyzed by four enzymes. The reaction system of Pyrophosphoric acid sequencing technology consists of reaction substrate, single strand to be tested, sequencing primers and four enzymes....
In an SN1 reaction, a carbocation is formed, which undergoes nucleophilic attack by the nucleophile. The nucleophile attacks the carbocation from both faces of the planar carbocation and produces two enantiomers in an equal amount. Answer and Explanation:1 ...
D-Galactose is an aldohexose that occurs naturally in the D-form in lactose, cerebrosides, gangliosides, and mucoproteins. D-Galactose is an energy-providing nutrient and also a necessary basic substrate for the biosynthesis of many macromolecules in the body. Metabolic pathways for D-galactose ...
