Enzyme activity can be inhibited. Name the two types of inhibition.
|
Competitive and non-competitive. |
|
Explain how competitive inhibition works. |
|
|
[competitive inhibition] What are the effects of increasing inhibitor concentration?What are the effects of increasing substrate concentration? |
|
|
Explain how non-competitive inhibition works. Explain if they are competing with substrates. What effect would increasing the substrate concentration have? |
|
|
Inhibitors can be reversible or non-reversible. What factors determine this?
|
|
|
Some drugs and metabolic poisons are enzyme inhibitors. Give two examples of medicinal drugs that are enzyme inhibitors. |
Medicinal drugs:
|
|
Some drugs and metabolic poisons are enzyme inhibitors. Give three examples of metabolic poisons that are enzyme inhibitors. |
|
|
What is a metabolic pathway? |
A metabolic pathway is a series of connected metabolic reactions. The product of the first reaction takes part in the second reaction and so on. Each reaction is catalysed by a different enzyme. |
|
What is product inhibition? |
When an enzyme is inhibited by the product of the reaction they catalyse. |
|
What is end-product inhibition? |
End-product inhibition is when the final product in a metabolic pathway inhibits an enzyme that acts earlier on in the pathway, breaking the chain and stopping the process. |
|
Is end-product inhibition reversible or irreversible? |
Reversible. |
|
Is product inhibition reversible or irreversible? |
Reversible. |
|
How is end-product inhibition a good way of regulation in the body? Give an example of end-product inhibition regulating in the body. |
|
|
How can enzyme inhibition protect cells? Give an example. |
