Question 5.

Sodium fluoroacetate, or compound 1080, is a rodent poison that probably disrupts the citric acid cycle. In the body, the molecule is converted to a compound that prevents citrate from being used. Initially, when first exposed to this molecule, what is the theoretical energy produced per glucose molecule through the process of cellular respiration?
