part 3 Flashcards
When substrate is constant, what happens if we increase enzyme concentration
The rate increases linearly
When enzyme concentration is constant, what happens if we increase substrate concentration
a Curve
What effects enzyme activity because it changes the conformation of the enzyme
Temperature
Each enzyme operates best at _______
A certain pH
A model explaining the specificity of enzyme action
by comparing the active site to a lock and the substrate to
a key.
Lock and Key Model
this model is where the enzyme is a rigid three-dimensional body. The enzyme surface contains the active site.
Lock and Key Model
A model explaining the specificity of enzyme action
by comparing the active site to a glove and the substrate
to a hand.
Induced Fit Model
this model is where he active site becomes modified to accommodate the substrate.
Induced Fit Model
When a competitive inhibitor enters the active site, the
_________ cannot enter.
Substrate
what is the term for when a non competitive inhibitor sticks to a site OTHER then the active site
Allosterism
what happens when allosterism happens?
the structure or conformation of the enzyme changes
When non competitive inhibitor binds to the enzyme, does the substrate bind to the active site?
yes, but no catalysis happens
