Isomerase - Study guides, Class notes & Summaries

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...

If the G'° of the reaction A -> B is -40 kJ/mol, under standard conditions the reaction: A) is at equilibrium. B) will never reach equilibrium. C) will not occur spontaneously. D) will proceed at a rapid rate. E) will proceed spontaneously from left to right. - E) will proceed spontaneously from left to right. For the reaction A - B,G'° = -60 kJ/mol. The reaction is started with 10 mmol of A; no B is initially present. After 24 hours, analysis reveals the presence of 2 mmol o...
