1. Metabolic Pathways and their Control - Control of Metabolism Through Regulation of Enzyme Action Flashcards
1
Q
How is non-competitive inhibition or stimulation enzyme activity modified?
A
By the binding of molecules to the enzyme that change the shape of the active site
2
Q
What is competitive inhibition?
A
When molecules that resemble the substrate compete with the substrate to enter the active site
3
Q
How is competitive inhibition reversed?
A
by increasing substrate concentration
4
Q
What is the control of metabolic pathways by feedback inhibition?
A
Where an end product binds to an enzyme that catalyses a reaction early in the pathway
5
Q
What does it mean when an enzyme is continuously expressed?
A
it means that these enzymes are always present in the cell and must be controlled through the regulation of their rates of reaction
