Enzymes, These are the enzymes
Leave substrates behind
These are the enzymes
Enzymes,
Reduce reaction
time
Leave substrates
behind
These are the
enzymes
Enzymes are proteins usually ending in “ase”
They change but are not changed, the
definition of a catalase
Combine with
substrates to
break them
apart
Their specific
activation site
makes sure
they hit the
mark
If there’s a
reaction that
you want to
go
Without an
enzyme it
reacts too
slow
Enzymes lower
activation energy
And once that’s
lowered, you’re
home free
(home free)
Enzymes, These are the enzymes
Leave substrates behind
These are the enzymes
Enzymes, Reduce Reaction Time
Leave substrates behind
These are the enzymes
Amino acids are the monomers
of a polypeptide - a protein polymer
Enzyme and
substrate fit
neatly in place
They got the
“Lock & Key”
to win the
reaction race
They require a
specific
temperature
And if it’s not exact
they can be
denatured
A proper pH
is necessary
If your acids
and bases are
just right,
you’re home
free
(home free)
Enzymes, These are the enzymes
Catalyze & metabolize
These are the enzymes
Enzymes, Reduce reaction time
Leave substrates behind
These are the enzymes

6. Which statement best describes the enzyme represented in the
graphs below?
A. This enzyme works best at a temp. of 35 C and a pH of 8.
B. This enzyme works best at a temp. of 50 C and a pH of 12.
C. Temp. and pH have no influence on the activity of this enzyme.
D. This enzyme works best at a temp. above 50 C and a pH above
12
Have you ever
known someone
to get ill?
If eating ice cream
or milk or
cheese they’d
have to take a
pill
That’s cause they
didn’t have the
protein lactase.
The enzyme that
digests lactose
and puts it in it’s
place
Have you ever
wondered how
your clothes get
clean?
With a little
detergent in a
washing machine
There are some
enzymes that will
break down the
grime
In all those awful
stains that give you
a real hard time.
Enzymes
Lactase, catalase,
protease,
Amylase, lipase,
pectinase,
Cellulase, maltase,
DNAse
