Enzymes Flashcards
What kind of reactions do enzymes help with
Metabolic reactions
What do enzymes do
Increase the speed of reactions
What is a catalyst
A catalyst is a substance that increases the rate without being used up(used as many times as it wants)
Why do enzymes speed up reactions
Requires a smaller amount of activation energy which makes reactions quicker
In what protien state are enzymes in
Tershiry or cortinary
What is induced fit
A enzyme tightens to the substrate to make a even tighter fit
If a enzyme changes chaps this means it’s been
Denatured
What do PH and temperature do to an enzyme
Denatures them
Non competitive inhibition
Binds to allosteric site changes the shape of enzyme
Competitive inhibition
A inhibitor that is similar size and shape to a substrate which connects to the enzyme which makes the enzyme unable to attach to a substrate
Feedback inhibition
Stopping an end products production by using a substrate in the pathway to attach to the allosteric site of the first enzyme stopping the creation process
Cofactors
Nonprotien and help enzymes in some cases to complete a reaction
Examples like zinc
Coenzymes
Same as cofactors but like vitamins
