24 Questions
What is the effect of an inhibitor binding to an enzyme?
Decreases the enzyme's activity
In which type of inhibition does the inhibitor bind at an allosteric site?
Noncompetitive inhibition
What did Anselme Payen discover in 1833?
Diastase
How do enzymes reduce the energy of activation in a reaction?
By facilitating the reaction through interaction at the active site
Which environmental condition may influence enzyme activity?
Temperature
How do enzymes help regulate a metabolic pathway?
By decreasing the energy of activation
What is the purpose of the energy of activation in a chemical reaction?
To prevent molecules from spontaneously degrading
How does substrate concentration affect enzyme activity?
It increases enzyme activity due to more frequent collisions with the enzyme
Why are most enzymes optimized for a particular pH?
To ensure maximum enzyme activity
What effect does temperature have on enzyme activity?
It increases enzyme activity at warmer temperatures
What is the main role of enzymes in a metabolic pathway?
To prevent molecules from degrading spontaneously
How does substrate concentration affect enzyme activity?
It increases enzyme activity due to more frequent collisions with substrate molecules
What effect does temperature have on enzyme activity?
It decreases enzyme activity as it denatures and destroys enzymes
What is the purpose of the energy of activation in a chemical reaction?
To initiate the reaction by adding energy to at least one reactant
Which factor influences an enzyme's rate of reaction by optimizing protein digestion?
pH
What happens when an inhibitor binds to an enzyme?
It prevents the substrate from binding to the enzyme
What is the effect of temperature on enzyme activity?
It increases enzyme activity
In which type of inhibition does the inhibitor bind at an allosteric site?
Noncompetitive inhibition
What is the role of enzymes in metabolic pathways?
They increase the speed of chemical reactions
