An enzyme cannot be used in any random reaction, the active site on an enzyme can only catalyze certain substances. Think of them as keys that only work for 1 lock.

What simple experiment might you perform to test the hypothesis that an enzyme combines with its substrate when it acts?

You could perform a simple enzyme activity assay. Mix the enzyme with its substrate and monitor the reaction rate over time using a spectrophotometer to measure any changes in absorbance or using a colorimetric assay to detect product formation. Compare the reaction kinetics with a control group lacking either the enzyme or the substrate to determine if the enzyme-substrate combination is necessary for the reaction to occur.


Why NaOH is used as stop solution to determine specific activity of alkaline phosphatase?

NaOH is used as a stop solution in determining the specific activity of alkaline phosphatase because it effectively denatures the enzyme, halting its activity. This allows for the accurate measurement of the enzyme's activity at a specific point in time. NaOH also helps in maintaining a constant pH, which is crucial for the accurate determination of enzyme activity. Additionally, NaOH stops any further substrate conversion, ensuring that the specific activity of alkaline phosphatase is accurately calculated.


What determines the shape of an enzymes active site?

The shape of an enzyme's active site is determined by its amino acid sequence, which folds into a specific three-dimensional conformation. This unique shape allows the enzyme to interact selectively with its specific substrate, forming an enzyme-substrate complex for catalysis to occur. Any alterations to the active site's shape can affect the enzyme's function.


Why a spontaneous chemical reaction is not necessarily a fast reaction?

No. A spontaneous reaction is one that will happen given enough time - it doesn't need any energy or enzyme to make it happen. For instance, the decomposition of carbonic acid (H2CO3) into water and carbon dioxide (H2O and CO2) is spontaneous. However, it can be reversed by an enzyme called carbonic anhydrase; it just takes energy.


Use catalyst in a sentence?

A catalyst is a substance that causes or aids in any type of reaction. Here are some sentences.That enzyme words as a catalyst in your body.She was the catalyst that started the argument.A catalyst is needed to make this chemical reaction occur.

Why is sand used in an enzyme rate of reaction lab?

Sand is used in an enzyme rate of reaction lab to provide a stable surface for the enzyme reaction to occur. It helps to maintain a consistent and controlled environment for the reaction by providing a solid base and preventing any unwanted movement or fluctuations. This ultimately allows for more accurate measurements and observations of the enzyme reaction rate.


What is a specific enzyme?

A specific enzyme is an enzyme that only changes the speed of ONE reaction. (It only acts on one particular substance that happens to be compatible with that enzyme) i.e. if enzyme A is specific to reaction A, it will change the speed of reaction A. However it will have no effect on any other reaction like reaction B or C.


After the enzyme catalyzes the reaction is it changed in any way?

The enzyme does not undergo any permanent changes during the catalytic reaction; it simply facilitates the reaction by lowering the activation energy. At the end of the reaction, the enzyme is released unchanged and can participate in further reactions.


What kind of enzyme can increase the rate of a chemical reaction?

Any, that is their function.

What does the shape of an enzyme have to do with how well the enzyme works?

The shape of an enzyme is crucial for its function because it determines the enzyme's specificity and ability to interact with its substrate. The specific shape allows the enzyme to bind to its substrate, facilitating the reaction. Any changes in the enzyme's shape can affect its ability to catalyze the reaction effectively.


The primary function of an enzyme or any biological catalyst is to?

The primary function of an enzyme or any biological catalyst is to increase the rate of a chemical reaction by lowering the activation energy barrier, thereby facilitating the conversion of substrate molecules into products. This process allows cells to efficiently carry out metabolic reactions necessary for growth, maintenance, and energy production.


What is the function of the enzyme catalyse?

is to catalyse or increase the rate of reaction without any change in itself .


Can an enzyme catalyze any reaction?

No, enzymes are specific in their function and can only catalyze specific reactions.


When an enzyme catalyzes a reaction does it become a product?

biological catalysts known as enzymes are molecules that lower the amount of energy required to kick start a reaction and are NOT used up or changed in the reaction.


What effect does substrate and enzyme joining have on chemical bonding?

enzyme catalyze the biochemical reactions by lowering their activation energy. An enzyme which take part in such reaction wont be lost or gained any chemical structure and it would be the same after the reaction.


Why are enzymes three dimensional shape so important?

An enzyme's three dimension shape is important to the binding that occurs between the enzyme itself and its specific substrate, forming the enzyme-substrate complex. In order for the enzyme to create a reaction it is important that the shape of the enzyme binds the substrate to the active site where the chemical reaction occurs. One other thing to consider is the shape that the enzyme takes that allows only its specific substrate to bind and not any other molecule.
