enzymes Flashcards
dss
enzymes are
catalyst
they increase?
rates
without being?
used up
most enzymes are?
globular proteins
An enzyme changes?
activation energy of a reaction
What is activation energy
Energy needed to activate reactant to form products
At what moment does the enzyme ha a better affinity ,substrate,product,transition state?
at the transition state
What does change?
delta G
if the delta G is positif?
rx less favorable and not spontaneous
is delta G is negative?
rx favorable and spontaneous
the interactions btw enzyme and substrate?
- Stabilize the transition state
- lower activation energy
the delta G formule is
G=Gf-Gi
before rx, reactants need to collide?
in a precise orientation
Also, to have enough
kinetic energy to overcome repulsion btw e that come into contact as a bond forms
where does the substrate binds?
active site (binding site)
