20. ENZYME

21. Enzymes
Enzymes are proteins that are used by the cell to speed up and regulate metabolic reactions. Enzymes are biological catalysts that remain unchanged by the reaction.

25. Enzymes
The substrate is temporarily bound to its enzyme at the active site. The enzyme may change shape slightly to accommodate the substrate.

26. ENZYMES ARE VERY PICKY!!!! ENZYMES ARE VERY PICKY. TEMPERATURE
IF IT GETS TOO HOT, TOO COLD –
THEY CHANGE SHAPE pH
IF IT BECOMES TOO ACIDIC – IF
