Enzymes
Catalyze
chemical reactions,
speed
them up
Enzymes
Large protein molecules
Have a
groove
on their surface called the
active site
The
active site
is where the
substrate
attaches
Substrate
The molecule that the enzyme
breaks down
Substrate
fits into
active
site
Enzyme can
break
down
substrate
Substrate
does not fit into
active
site
Enzyme
cannot break down
substrate
Lock
and
key theory
Enzymes are specific, the substrate must
fit perfectly
into the
active site
Proteins
Long chains of chemicals called
amino acids
Carbohydrases
Enzymes that
break
down
carbohydrates
Amylase
breaks down
starch
Starch
A carbohydrate consisting of a chain of
glucose
molecules
Lipases
Enzymes that break down
lipids
Found in the
pancreatic
fluid and
small
intestine
Lipids
Molecules consisting of
glycerol
attached to
three
fatty acids
Lipid
digestion
Lipase
breaks down lipids into glycerol and
fatty acids
Bile
Made in the
liver
, stored in the gallbladder
Not an
enzyme
, but helps
speed
up lipid digestion by
lipase
Converts
large lipid droplets
into
smaller droplets
, increasing surface area
Alkaline,
neutralizes stomach acids
in the
small intestine
