Consider the two metabolic reactions below:

reaction 1: a + b → c δg˚ = 8.8 kj/mol

reaction 2: c → d δg˚ = -15.5 kj/mol

if reaction 1 and 2 are coupled, what would the net reaction be?
choose one:
a. a + b + c → d
b. a → d
c. a + b → c + d
d. a + b → d

the net reaction would have δg˚ =

kj/mol.
