4.1 Study Guide Flashcards
Substrate
The reactants in a chemical reaction
Enzyme
Speeds up a chemical reaction
Active Site
Where the substrate and enzyme come together.
Activation Energy
How much energy a reaction needs to take place
What is the relationship between reaction rate and substrate concentration?
The substrate concentration and reaction rate rise together and fall together, they are best the graph looks like an upside-down u.
What is the relationship between reaction rate and Enzyme Concentration?
The Enzyme concentration and reaction rate rise together and fall together, they are best the graph looks like an upside-down u.
What is the relationship between reaction rate and Temperature?
The optimal temperature for reaction rate is around 40 degrees because it is the most neutral.
What is the relationship between reaction rate and pH?
The optimal pH for reaction rate is 7 because it is neutral and not too acidic or basic.
What does an inhibitor do to an activation site.
When an inhibitor is present, the activation site gets changed so that it isn’t possible to bind with a substrate.
What happens to Enzyme rates when you change various conditions?
When various conditions are changed, they will increase until they get to their optimal point and then will begin to decrease.
