What is the definition of metabolism? |
all the chemical reactions (RXNs) in your cell
|
|
|
What are metabolic pathways? |
a series of rxns which occur in a step-by-step manner |
|
|
How are metabolic pathways regulated? |
Activation or deactivation of the enzymes
|
|
|
Why might the end product of a metabolic pathway inhibit a enzyme involved in it? |
To control the pathway with negative feedback |
|
|
What determines an enzymes action? |
the structure of the enzyme |
|
|
What is an enzyme active site? |
the area of an enzyme which interacts with the substrates in a specific manner |
|
|
How do enzymes work? |
Enzymes decrease the energy of activation by bringing substrates closer together |
|
|
What is the overall reaction of enzymes? |
Enzyme + substrate <--> Enzyme-substrate complex --> Enzyme + product |
|
|
What would happen to a reaction that had an increase in substrate? |
Products will increase until the enzyme is saturated |
|
|
What would happen to a reaction that had an increase in enzymes? |
concentration of products will increase only if the substrate is adequate |
|
|
What are inhibitors? |
molecules which have similar shape to the substrate |
