Enzymes are proteins ____________________________________

____________________________________ each enzyme needs to be the ___________

for the job enzymes are named for the reaction

they help ___________ breaks down ___________ ___________ breakdown ___________ ___________ breakdown ___________ ___________ builds ___________

Oh, I get it!They end

in -ase

Enzymes aren’t used up ____________________________________

used only temporarily re-used again for the same reaction with

other molecules very little enzyme needed to help in many

reactions
