An interaction between two subunits of a protein was determined to have a Delta G degree = -57.05 kJ/mol. What is the K_eq tor the reaction at 25 degree C? a. 1.02 b. 1.32 c. 10-10 d. 10^16 e. cannot determine from given information To predict whether pairs of coupled reactions will proceed spontaneously: a. Subtract the smaller from the larger Delta G. b. Sum the Delta G degree for each reaction. c. Add the Delta S values for each reaction at constant temperature. d. The absolute value of the positive Delta G degree must be larger than the value of the negative Delta G degree. e. None are true. Based upon the following reactions, what would be the Delta G degree for the formation of ATP from phosphenolpyruvate and ADP? ATP rightarrow ADP + Pi Delta G degree = -31.5 kJ/mol phosphoenolpyruvate rightarrow pyruvate + Pi Delta G degree = -62.2 kJ/mol a. -93.7 kJ/mol b. -30.7 kJ/mol c. +30.7 kJ/mol d. +93.7 kJ/mol e. cannot determine from given information.
