Metabolism
The sum of all chemical reactions in an organism that involve getting and using energy
Metabolic pathway
An assembly of chem reactions where enzymes are the “workers”
Why do cells need metabolic pathways?
Enzymes are only capable of making small changes, so for a big change it needs more steps
Example of metabolic pathway?
A -> B -> C -> D
From A to D
How does the body get rid of toxic metabolites such as h2o2?
Catalase/yeast
How does a cell know when to turn on or off an enzyme?
Allosteric reaction
Allosteric reaction
The binding of a regulatory molecule to separate the Allosteric bind to turn off an enzyme by changing the shape of the active site
How do cells know when to stop making a product?
Feedback inhibition
Competitive inhibitions
Interferes w/ the active site so the substrate can’t bund
Noncompetive inhibitions
Bonds to a site other to an active site, causes the enzyme to change shape
