Metabolic pathways Flashcards
What is an anabolic reaction
Build up of large molecules from small molecules and requires energy.
What is a catabolic reaction
Break down of large molecules into smaller molecules and releases energy.
What do enzymes do
Lower the activation energy for a reaction
What is induced fit
Where the active sire changes shape to better fit the substrate after the substrate binds.
What do competitive inhibitors do
Bind at the active site preventing the substrate from binding.
How can competitive inhibition be reversed
Increasing substrate concentration
What do non competitive inhibitors do
Bind away from the active site but change the shape of it preventing substrate from binding.
What is feedback inhibition
When product in a metabolic pathway reaches a critical concentration.
Then end product then inhibits an earlier enzyme, blocking the pathway and is prevents further syntheses of the end product.
