When graph plateaus
No matter how much more substrate you add there are no free active sites to increase when plateaus
Low substrate concentration
Free active sites/ space to be filled
Less enzymes equals
Slower reaction rate
Compatible inhibitor
Molecules bind reversibly or irreversibly to active site of enzyme completes with normal substrate
If competivte inhibitor inhibits more than substrate
Reactions slowed
If competivte inhibitor inhibits less than substrate
Substrate reactions can proceed normally
If inhibitory binding irreversible
Enzyme function prevented
If inhibitory binding reversible
Can regain function
Other region enzymes bind to
allosteric site
Noncompetive inhibtots do not bind to
Active site but bind to allosteric site
Binding causes conformational shape
Binding prevents enzyme functions because the active site is no longer available
Reaction rate decreases
Enzymes that can be regulated have an additional are called
Allosteric site
Downstream products bind to regulatory site causing
The enzyme to change shape and prevent it form binding with its substrates causing pathway to halt new products no longer formed
Energy is
Never created or destroyed
When energy converts from one form to anothe r
Heat is lost
One may bring
Energy one may spend
