ENZYMES ARE PROTEINS
Organic molecules
Made up of amino acids
Proteins are coded for by
genes made of DNA

Enzymes have a
particular shape
designed for their
substrate
Only work at certain
pH or temperature
ENZYMES ARE SPECIFIC

Breaks down the sugar
lactose into simple
sugars
Lactose is the sugar in
milk

Artificial form of lactase
Taken in pill or drop form
by those who are “lactose
intolerant”
Those who do not
synthesize enough lactase
LACTAID

Found in plants and algae
Takes CO2 molecules and
combines them into glucose
Most abundant enzyme on
Earth
RUBISCO

Breaks down large
molecules into small
molecules
Small molecules like
glucose can be absorbed
into the blood
Large molecules like
starch are too big to be
absorbed
