ENZYMES
Who cares?
ENZYMES
speed up chemical reactions
put chemicals together (synthesis reactions)
break chemicals apart (decomposition)
CHEMICAL REACTIONS
Like….
CELL RESPIRATION
PHOTOSYNTHESIS
FERMENTATION
C6H12O6 CH3CH2OH +
CO2+ ATP
glucose ethanol
ENZYMES ARE PROTEINS
Organic molecules
Made up of amino acids
Proteins are coded for by
genes made of DNA
ENZYMES
Enzymes have a
particular shape
designed for their
substrate
Only work at certain
pH or temperature
ENZYMES ARE SPECIFIC
THE ENZYME HALL OF FAME
Powerful proteins!
LACTASE
Breaks down the sugar
lactose into simple
sugars
Lactose is the sugar in
milk
LACTASE
Artificial form of lactase
Taken in pill or drop form
by those who are “lactose
intolerant”
Those who do not
synthesize enough lactase
LACTAID
SUCRASE
AMYLASE
Alpha-amylase Glucoamylase
THE ROLE OF AMYLASE
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
DIGESTIVE SYSTEM
PHOTOSYNTHESIS
THE SITE OF PHOTOSYNTHESIS: THE
CHLOROPLAST
