Enzymology Exam 1 study guide Questions & answers

Catalyst - 1. Chemical or biological substance or structure that lowers activation energy 2. Accelerates the rate of a chemical rxn Enzymes - Biological catalysts that are capable of performing multiple rxns (are recycled). They can be proteins or RNA, are faster than chemical catalysts, and act under mild conditions (bodily temperature/pressure). They are highly specific and tightly regulated. Enzyme functions - - cell shape and motility - surface receptors - metabolism - cell cycling ...

Which of these statements is correct? A) A catalyst decreases the activation barrier by different amounts for the forward and reverse reactions. B) A catalyst decreases the activation barrier by the same amount for both the forward and reverse reactions. C) A catalyst increases the activation barrier by different amounts for the forward and reverse reactions. D) A catalyst increases the activation barrier by the same amount for both the forward and reverse reactions. E) A catalyst does ...

enzymes increase reactions by lowering the activation energy-which is the energy needed to go from the reactant to the transition state. The transition state is called the enzyme substrate complex - function of enzymes Classes of enzymes: oxidoreductase-oxidation/reduction reactions, transferase-group transfer reaction, hydrolase-hydrolytic reactions, lyase- cleavage of C-C C-S C-N bonds, isomerase- isomerization, ligase-condensation of two molecules coupled with cleavage of ATP. - class of...
