Enzymes as catalysts-Chapter 18E.T. DenisovO.M. SarkisovG.I. Likhtenshtein
how do enzymes function? enzymes act as biological catalysts (biocatalysts). catalysts accelerate chemical reactions. the molecules upon which enzymes may act are called substrates, and the enzyme converts the substrates into different molecules known as products. almost all metabolic processes in the ...
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 ...

Which of the statements regarding enzymes is false? a. Enzymes are proteins that function as catalysts. b. The activity of enzymes can be altered by the presence of inhibitors and activators. c. Enzymes display specificity for certain molecules to which t ...
Enzymes function by lowering the activation energy (the energy required to initiate the reaction) of a reaction. As is the case with all catalysts, they are not permanently altered during the catalytic process.Answer and Explanation: (a) Various factors can affect the ...
Nature's catalysts have been extensively studied as catalysts for polymerization reactions such as polycondensations, ring-opening polymerizations, and free radical polymerizations.[1,2] However, enzymatic activity in controlled radical polymerizations, such as atom transfer radical polymerization (ATRP),...
