Cards

Term
Enzymes: 2 factors
Definition
1: thermodynamics - whether or not the reaction will happen. 2: kinetics - how fast the reaction will happen
Term
Free energy
Definition
deltaG. deltaG < 0, the reaction is spontaneous (will occur). deltaG > 0, the reaction will not happen. deltaG = 0, the reaction is at equilibrium.
Term
Equilibrium
Definition
When the forward and backward reactions go at the same rate.
Term
K eq
Definition
concentration of products/ reactants; % completion
Term
deltaG 0'
Definition
-RT ln(Keq)
Term
completion of reaction
Definition
defined when it reaches equilibrium
Term
convert ln to log10
Definition
multiply by 2.303
Term
how to make a reaction spontaneous if it is not
Definition
change concentration of products or reactants
Term
transition state
Definition
point of a reaction where the molecule is between the products and reactants
Term
activation energy
Definition
the energy required to reach the transition state/ create the reaction
Term
what enzymes do for the reaction
Definition
lower activation energy by bringing reactants into correct orientation. free energy of reaction does not change
