Which statement best describes the reason why some of the reactions of glycolysis cannot be run in reverse in gluconeogenesis? The last reactions occur in mitochondria and reactions there can never be 1) reversed. 2) Glycolysis includes isomerization reactions and these can never be reversed. O 3) There are some allosteric enzymes and allosteric enzymes can never be reversed. 4) Some reactions have such large negative free energy changes that they can never be reversed under cellular conditions.
