enzymes
specific
active site
the active site is the part where an enzyme and its substrate meets
enzymes are specific to their substrate because each have their own job
enzymes are proteins
found in all living cells
enzymes speed up chemical reactions
they do not get used up
without them we would die because it would take too long for reactions to happen
types of reactions
fats ----------> fatty acids
proteins ---------> amino acids
carbohydrates ----------> sugar
pepsin
amylase
lipase
experiments
liver, onion and carrot when added to hydrogen peroxide will foam. this shows there was a chemical reaction due to there being an enzyme called catalse.
hydrogen peroxide is a waste product our bodies produce and is toxic so an enzyme brakes it down quickly to get rid of it.
