Enzymes are catalysts because they operate to ___.Why are enzymes critical to the function of cells? In other words, why not simply let chemical reactions occur without interference?Why are enzymes essential to cellular biochemistry?Why are vitamins considered co-enzymes? a. They are organic and...
Enzymes are biological catalysts of the protein nature, which accelerate chemical reactions and are necessary for the living activity of organisms. Enzymatic catalysis is characterized by high substrate specificity (in some cases, stereospecificity), selectivity with respect to specific bonds of the ...

ENZYMES What’s an Enzyme? Enzymes are proteins. Enzymes are catalysts. Catalysts speed up chemical reactions End in –ase (Ex: sucrase, catalase) Without an enzyme! With an enzyme! WARNING Superman had Kryptonite Enzymes have Acids (pH) Cold Temperatures Extreme Hot Temps slow down the enzyme...
Enzymes are now an attractive proposition as catalysts for new classes of reagents and products, especially sugars, chiral synthons, metabolites and food components. This article discusses the applications of enzymes in the synthesis of compounds such as chiral epoxy alcohols, chiral butene oxide, ...
Why are enzymes considered organic? Catalysts: Catalysts are key to many reactions both in chemistry and in biology. They speed up or lower the activation energy needed for a reaction to occur, without being used up in the process. Answer and Explanation: ...
