Metabolic pathways should be thought of as porous—that is, substances enter from other pathways, and intermediates leave for other pathways. These pathways are not closed systems. Many of the substrates, intermediates, and products in a particular pathway are reactants in other pathways.

One molecule of ATP (or an equivalent) is produced per each turn of the cycle. The electron transport chain is the portion of aerobic respiration that uses free oxygen as the final electron acceptor for electrons removed from the intermediate compounds in glucose catabolism.

The pathway is cyclic and thus, does not really have a starting or ending point. All of the reactions occur in mitochondria, though one enzyme is embedded in the organelle’s inner membrane. Cells may use a subset of the reactions of the cycle to produce a desired molecule.

The resulting acetyl-CoA can enter any one of several pathways for the biosynthesis of larger molecules. We will focus on its routing to a central metabolic pathway called the Citric Acid Cycle. Here the remaining two carbons in the acetyl group can either be further oxidized or serve as precursors for the construction of various other molecules.

Glycolysis in eukaryotes, as be ts its prokaryotic origins, happens in the cytoplasm. The TCA cycle (also called the citric acid cycle) happens inside the matrix of the mitochondria, a double-membraned organelle.

It highlights mitochondrial DNA (mtDNA) mutations as a cause of diseases, influenced by heteroplasmy. Mitochondrial Replacement Techniques are being studied to prevent the transmission of defective mtDNA from mothers.
