Which reaction we can use isomerase enzyme?

Isomerase enzymes catalyze reactions where structural rearrangement of molecules occurs. Examples include converting glucose-6-phosphate to fructose-6-phosphate in glycolysis by phosphoglucose isomerase, and converting citrate to isocitrate in the citric acid cycle by aconitase.


What does the presence of an enzyme cause?

Enzymes are biological catalysts which cause the rate of a reaction to increase (by providing an alternate reaction pathway with a lower activation enthalpy). They are very specific to the reaction they catalyse.


How does enzymes catalyze a chemical reaction?

by lowering activation energy to increase the reactionEnzymes are biological catalysts, and can hence lower the activation energy barrier of the reaction that it catalyses. Enzymes do this in several ways:1) Enzymes can provide a suitable environment for the reaction to take place. The active site of a enzyme can be highly acidic (pH


How do enzymes affect chemical reaction?

Usually enzymes have the role to catalyse a reaction. That means they aren't changed at all, but they influence the mechanism to reduce the activation energy (the energy needed for the reaction). The reaction is therefore performed more easily. To put it very simply: It speeds up a chemical reaction.


Enzymes are examples of?

biological catalysts that speed up chemical reactions by lowering the activation energy needed for the reaction to occur. They are specific in their action, often catalyzing only one type of reaction or a set of closely related reactions.

Is enzymes slow the rate of reaction?

Actually, enzymes are typically used to catalyse a biological reaction, leading to a faster reaction rate, not slower.


What does reusable enzymes mean?

Enzymes aren't used up or denatured after they catalyse a reaction.


How do catalysts catalyse the reactions?

They lower the activation energy needed to kick off the reaction and hence make the reaction proceed faster.


What is an aconitase?

Aconitase is another name for aconitate hydratase, an enzyme which catalyzes the stereospecific isomerization of citrate to isocitrate via cis-aconitate in the tricarboxylic acid cycle.


What is the end product of arginine hydrolysis?

The end products of the hydrolysis of Arginine are Orthinine and urea, several enzymes catalyse this reaction the easiest to remember is arginase.


Are substrate and catalyse the same thing?

No! A substrate is a reagent in a chemical reaction. Catalyse is the verb form of catalyst; a catalyst is a chemical species that participates in lowering the energy barrier of a chemical reaction and allow a reaction to occur more rapidly. A catalyst is not consumed in a reaction and therefore only a small amount of catalyst is required in any reaction (if required at all), whereas a substrate must be present in the proper stoichiometric amount to allow a reaction to proceed as it is consumed.
