18 Questions
What is the function of the active site in an enzyme?
To bind with the substrate
How does the unique geometric shape of an enzyme's active site contribute to its function?
It helps the enzyme react with a specific substrate
What is the role of activation energy in a chemical reaction catalyzed by enzymes?
Provides the minimum energy required to start the reaction
How are enzymes named according to nomenclature standards?
Derived from their substrates or reactions, with 'ase' as a suffix
What is the primary function of enzymes in chemical reactions?
To decrease activation energy
How do enzymes achieve specificity in their reactions?
By having a unique geometric shape in their active site
According to the Lock and Key Theory, what does the lock represent?
The enzyme
Which theory suggests that the substrate can influence the final shape of the enzyme?
Induced Fit Theory
What is the main role of the active site in an enzyme?
To specifically bind to the substrate
Why do certain compounds fail to react with enzymes according to the Induced Fit Theory?
Because the compounds distort enzyme shape too much
How do enzymes help in lowering activation energy during a reaction?
By providing an alternative reaction pathway
What determines the specificity of an enzyme towards a particular substrate?
The alignment of the active site with the substrate
What is the main function of enzymes?
Facilitate biochemical reactions
What is the specific pocket on an enzyme where the substrate binds known as?
