The Krebs cycle occurs in the? Where does Krebs cycle and electron transport system occur? Both occur inside an intracellular inclusion, or organelle, known as a mitochondria. More specifically, the Kreb's cylce (also called the citric acid cycle) occurs in the mâ¦atrix(or inner space) of the mitochondrion.
