Question 20 of 30 Map Sapling Learning ma cmillan learning Glycolysis is the process by which energy is harvested from glucose by living things. Several of the reactions of glycolysis are thermodynamically unfavorable (nonspontaneous), but proceed when they are coupled with other reactions. (a) Which of these reactions is(are) unfavorable? Select all that apply A. Pi glucose glucose-6-phosphate+ H2O G=3.30 kcal/mol B. Pi + fructose-6-phosphate fructose-1,6-bisphosphate + H2O G=3.90 kcal/ mol C. ATP+ H,O ADP+P, G=-7.30 kcal/ mol (b) Which of these reactions can be coupled so that the overall reaction is favorable? Select all that apply. A and B A and C B and C

Explanation / Answer

a)

unfavorable are all those which

dG > 0, since are not going into products

then

choose A and B only

b)

if we couple A and B with C

we will have ATP --> ADP + Pi

which cnacels out and makes the process possilbe

dG = -7.30 + 3.3 = negative, i.e. possible

dG = -7.30 + 3.90 = negative, i..e possible
