What is the rate equation?
4 factors that influence enzymes
1) pH 2) temperature 3) enzyme concentration 4) substrate concentration
What is the Michaelis-Menton equation?
What are the three assumptions of the Michaelis-Menton equation?
1) The amount of substrate bound by the enzyme at one time is small. 2) [ES] does not change with time. (the steady-state assumption) 3) Only initial reaction rates are used in the analysis.
What is the specificity constant?
What is the Lineweaver-Burk equation?
1/Vo= Km/(Vmax[S]) + 1/Vmax
In competitive inhibition, the inhibitor binds to:
The active site of the enzyme.
In uncompetitive inhibition, the inhibitor binds to:
a site distinct from the active site and only to the ES complex.
In noncompetitive inhibition, the inhibitor binds to:
a site distinct from the active site and to the E or ES complex.
Which class of inhibitors: 1) has no effect of Vmax & 2) Increases Km
Which class of inhibitors: 1) Decreases Vmax & 2) Has no effect on Km
When the substrate that binds also causes an allosteric conformational change this is described as:
When the substrate that binds does not cause an allosteric conformational change, but allosteric conformational change is caused by a different modulator/effector this is described as:
In allosteric regulation, instead of using Km, we use a similar term called:
The competitive inhibitor of Tetrahydrofolate (THF) is:
