C3.4 Catalysts and enzymes Flashcards
what is the use of catalysts
they speed up chemical reactions without getting used up
what are enzymes used as
biological catalysts
what are enzymes made of
large protein molecules
what is vital for the enzyme to function
the shape
LOCK AND KEY: substrate of the reaction fits into where
the active site
LOCK AND KEY: once in place in the active site what happens
the enzyme and substrate bind together
LOCK AND KEY: what happens after the enzyme and substrate bind together
the reaction then takes place rapidly and the products are released from surface of the enzyme
what can enzymes do
join molecules together as well as break up large ones
what is your metabolism
sum of all chemical reactions in your body
enzymes control what
your metabolism
different enzymes speed up specific types of metabolic reactions such as
- building large molecules from lots of smaller ones
- changing one molecule into another
- breaking down large molecules into smaller ones
