The Standard Redox Potential of the NADP⁺/NADPH Half Reaction =

question 13

Multiple Choice

The standard redox potential of the NADP⁺/NADPH half reaction = -0.324 V. The standard redox potential of the fumarate/succinate half reaction = +0.031 V. What is the voltage change for coupling these redox reactions and in which direction will electrons move?

• A)0.355 volts; fumarate will be reduced to succinate and NADPH will be oxidized to NADP⁺
• B)-0.355 volts; fumarate will be reduced to succinate and NADPH will be oxidized to NADP⁺
• C)0.355 volts; succinate will be reduced to fumarate and NADP⁺ will be oxidized to NADPH
• D)-0.355 volts; fumarate will be oxidized to succinate and NADPH will be reduced to NADP⁺
