An
enzyme
is what type of macromolecule?
nucleic acid
carbohydrate
protein
What model has an
enzyme
fiting perfectly
with its
substrate
?
activation model
lock and key model
puzzle piece model
Pepsin (enzyme in stomach to digest food) works
best
at
pH of 2
.
Which graph best shows what will happen to the activity of pepsin as the pH of the stomach is
increased
?
Enzymes can only work with a particular substrate because...
the substrate and enzyme
permanently bond
an enzyme is only used once before it is
destroyed
the substrate and enzyme have
specific matching shapes
Choose all
that
affect
enzyme function (how well it works /
como se funciona
).
concentration of substrate or enzyme
the types of bonds found in the molecules
pH
temperature

activation energy
and decreasing ⬇ the
speed of reaction
denaturing the molecule
lowering ⬇ the
activation energy
and increasing ⬆ the
speed of reaction
At

lipase
denatured (stops working completely /
paren de trabajar
)?
