Metabolism refers to all of the chemical reactions that take place inside living cells. Unicellular and multicellular organisms must control their metabolism in order to survive.
What is the name of the molecules the cell uses to directly control metabolic pathways?
What type of reaction builds up larger molecules from smaller ones?
What type of reaction breaks down large molecules into smaller ones?
What process best describes the action of enzymes?
Lock and key theory
When the enzyme binds to the substrate, what happens to the activation energy of the reaction?
The activation energy is decreased
The activation energy is increased
The activation energy stays the same
Name the type of inhibition that occurs when an inhibitor molecule binds to the active site of the enzyme and stops the substrate from binding?
What is the type of inhibition that occurs when an inhibitor binds to a different part of the enzyme and changes the active site shape?
Which coloured line indicates the reaction rate of a non-competitive inhibitor?
Which coloured line indicates the reaction rate of a competitive inhibitor?
What term describes an end product in a metabolic pathway binding to an enzyme at the start of a metabolic pathway in order to stop the process?
