Which of the reactions are spontaneous (favorable)? glutamate + NAD+ +HO N H + a-ketoglutarate + NADH+H+ AG -3.7 kcal/mol CH,0 C,H,O, +H,0 AG = 3.1 kJ/mol CH,0,P + ATP C40P, + ADP AG = -14.2 kJ/mol DHAP glyceraldehyde-3-phosphate AG - 3.8 kJ/mol SEAR (I) CH+H, — C,H, AG = -150.97 kJ/mol L-malate + NAD+ oxaloacetate + NADH+H AG -29.7 kJ/mol U

Answer 1

the reaction are spotaneous, if change in free energy (delta G) is - ve. Only for 2 reactions deltaG is - ve, so these are spontaneous.

C6H13O9P + ATP ~~>C6H14O12P2 +ADP.

for this reaction deltaG is - 14.2 kJ/mol, hence

- ve, so spontaneous.

C2H4 + H2 ~~>C2H6 , deltaG = - 150.97 kj/mol, hence negative, so spontaeous.

All other reactions are not spontaneous, because deltaG is +ve for them.
