What simple experiment might you perform to test the hypothesis that an enzyme combines with its substrate when it acts?
in the absences of the enzyme the reaction is very slow,and at the end of the reaction enzyme is separated that shows substrate 1st bind to the enzyme
What enzyme converts glucose to ethanol during fermentation?
Zymase, found in yeast
What would be the effect on product formation if the enzyme were heated to a temperature of 100 degrees celsius for 10 minutes before repeating the experiment?
They would be stopped because the enzyme is denatured from the high temperature. High temperature usually speed them up, but after 45 degrees celsius it becomes denatured.
What is it called when and enzyme and substrate come together?
The binding of an enzyme and a substrate forms an enzyme-substrate complex. It lowers the activation energy of a chemical reaction
Is fructase an enzyme?
Yes, fructase is an enzyme.
What is an example of a sentence using the word 'enzyme'?
"During this experiment, we will be looking to see the effects of heat on enxyme activity" "This stain remover contains an enzyme"
What affect does too much substrate have on the rate of an enzyme reaction?
The enzyme becomes saturated by the substrate and enzyme activity plateaus.
If an enzyme in solution is saturated with substate What is the most effective way to obtain yield of produtct?
If an enzyme solution is saturated with substrate the most effective way to obtain a faster yield of products is to increase the enzyme concentration. An alternative is to increase the temperature.
Why acid hydrolysis of sucrose avoided during experiment with enzyme invertase?
Enzyme hydrolysis is better than acid hydrolysis because in enzyme hydrolysis eventhough the final product may contain some Enzyme it wont affectbut on the other hand acid is highly toxic
What has no effect on the rate of an enzyme-catalyzed reaction?
When an enzyme is saturated the amount of substrate added no longer as an effect on the rate of the reaction.
WHich action would most likely increase the rate of an enzyme-controlled reaction during an experiment?
raising the temperature from 20°C to 30°C
What simple experiment can you perform to test the hypothesis that an enzyme is not used up during the reaction?
Add more of the reactants under appropriate reaction conditions. If more product is made, this shows that the reactants are the limiting component and not the enzyme.
What is the purpose of the extracellular enzyme experiment?
Extracellular enzyme is an enzyme that performs its role or function outside a cell. The purpose of experimenting extracellular enzyme is to know how can it affect our body when the bacteria secretes.
In a paper on the catalytic activity of an enzyme, in which section would you find detailed information on how the enzyme was prepared and handled in the experiment?
materials and methods

What is the function of sulphuric acid in the experiment of enzyme activity?
H2SO4 is used to denature the enzyme and stop the reaction instantly. by adding H2SO4,it will prevent further reaction of the enzyme onto the substrate and the rate of enzyme reaction can be measured in the specific time
