Co - factors for enzymes Flashcards
What is a cofactor?
It is inorganic molecules that help enzymes with telling them what to catalyse the enzymes, helping the reaction rate
What is a prosthetic group?
A prosthetic group permanently covalently bond to the enzyme group
What is carbonic anhydrases prosthetic group?
Zinc ions
How is carbonic anhydrase and zinc bonded to each other?
It is permanently covalently bonded to each other
What does the zinc do to the carbonic anhydrase?
It catalyses O2 and CO2
How are cofactors bonded to the enzyme?
A cofactor temporarily covalently bond to the enzyme group
How are co substrates bonded to the substrate?
A cofactor temporarily covalently bond to the substrate group
Where are prosthetic groups on the enzyme?
The active site
What is a co-enzyme?
Organic non-protein molecules that binds to the enzymes active site
How does a co-enzyme bind to the enzyme?
It covalently temporarily bonded to the enzyme
When does a co-enzyme bind to the enzyme?
Either before or after the substrate is added, changing the reaction
What is chlorine a co - factor for?
Catalyse amylase
What is zinc a prosthetic group for?
Catalyse carbonic anhydrase
