Enzymes are _________________ that speed up or __________________ chemical reactions. enzymes are important because all living things must do many ____________________ in order to survive. the chemical reactions done by living organisms are known as ______________________________. in biology, the two most important types of reactions are _______________________ and __________________. __________________________ is a type of chemical reaction that involves the ________________________ of polymers into _____________________________. _________________________ is a reaction that involves ___________________________ large molecules by joining together building blocks called _________________________________. dehydration synthesis happens in your cells when you need to build large molecules such as _________________________, ______________________, or _____________________________. click on specificity tab each enzyme has a unique ______________________________ that makes an _____________________________ each active site can only fit a specific___________________________________ when a substrate(s) enters the active site, the enzyme helps a specific ________________________________ to occur. the end result of a chemical reaction is the ___________________________ or ________________________ what is the part of the enzyme where the substrate binds? ______________________________________________ we say that enzymes are specific. what does this mean? ________________________________________________ _______________________________________________________________________________________________
