Metabolism Flashcards
Reactions within metabolic pathways can be anabolic or catabolic. Which one breaks down large molecules into smaller molecules and releases energy?
Catabolic
Reactions within metabolic pathways can be anabolic or catabolic. Which builds up large molecules from small molecules and requires energy
Anabolic
Where does the substrate(s) bind to on an enzyme?
Active site
What is formed from an enzyme-substrate reaction?
Product(s)
When the active site of the enzyme changes shape to better fit the substrate after the substrate binds, what is this called?
Induced fit
What effect does induced fit have on activation energy?
Lowers it
Does the substrate(s) have a high or low affinity for the active site?
High
Does the substrate(s) have a high or low affinity for the active site?
High
Does the product(s) have a high or low affinity for the active site?
Low
Which type of inhibitor hinds to the active site preventing the substrate from binding?
Competitive
Which type of inhibitor binds away from the active site but changes the shape of the active site preventing the substrate from binding ?
Non-competitive
Which type of inhibitor binds away from the active site but changes the shape of the active site preventing the substrate from binding ?
Non-competitive
Which type of inhibition can be reversed by increasing substrate concentration?
Competitive
What is it called when the end product in the metabolic pathway reaches critical concentration and inhibits earlier enzyme, blocking the pathway, and so prevent further synthesis of the end-product?
Feedback inhibition
