"Which of the following describes pathways that would be active to provide molecules (NADPH and ATP) required for fatty acid synthesis upon insulin signaling?

a. Stimulation of the non-oxidative phase only by use of glycolytic intermediates.
b. Cycling of the oxidative and non-oxidative phase to produce NADPH only.
c. Stimulation of the oxidative phase to produce NADPH and the non-oxidative phase to produce glycolytic intermediates that can be used to generate ATP.
d. Stimulation of the oxidative phase to produce NADPH and ribose-5-P only."
