BIOC 3101 Lecture Notes - Lecture 1: Triosephosphate Isomerase, Atp Hydrolysis, Joule
Document Summary
Bioc 3101- lecture 10 &11 sample problems: an enzymatic hydrolysis of fructose-1-p was allowed to proceed to equilibrium at 25 c. The concentration of fructose-1-p was originally 0. 100 m, and reached an equilibrium concentration of 6. 50x10-5 m. calculate g " of this reaction. Fructose-1-p + h2o fructose + pi: consider the following coupled reactions: A b (keq = 2. 0x10-2 at 37 c); b c (keq =1. 0x103 at 37 c) Determine keq for the overall reaction a c, at 37 c. Which reactions are favorable and which are not: for a given reaction, the values g and g " could either be the same or different. Name a case where g > g ", and a case where g < g ": the hydrolysis of acetyl phosphate is highly favorable: Acetyl-phosphate + h2o acetate + pi + h+ ( g "=-43. 3 kj/mol) Calculate the g of this reaction if all conditions were at the biological standard state, except ph.
