During glycogen degradation glucose-1-phosphate is converted to glucose-6-phosphate and is an example of a coupled reaction. If the phosphoryl group transfer potential for glucose-1-phosphate is -20.9 kJ/mol and for glucose-6-phosphate is -13.8 kJ/mol, then what is the Keq (K) at 298 K? Is the conversion of glucose-1-phosphate to glucose-6-phosphate favorable or unfavorable under standard conditions?
ΔG° = -RT ln K where R = 8.315 x 10-3 kJ/mol*K
K = 0.057 and the reaction is unfavorable. |
K = 17.5 and the reaction is favorable. |
K = 0.057 and the reaction is favorable. |
K = 17.5 and the reaction is unfavorable. |
Answer:
To decide favourable or unfavourable
Here in biological transformation,
The value of equilibrium constant for the reaction is given as follows
i.e.,
- K = 17.5 & the reaction is favourable
So The reaction has a value
Thus the reaction is spontaneous or favourable.
So option B is correct
