Aerobic Respiration

Okay, so in aerobic respiration first there is 1 Glycolysis, then 2 Krebs/Citric Cycle, and then finally 3 Electron Transport Chain So when does oxidative phosphorylation occur? Like before or after the electron transport chain? Thanks!

During Krebs Cycle, it’s said that the process occurs in the mitochondria, but if the yeast undergoes aerobic respiration, where would the process happen? Yeast is a prokaryotic cells, so it doesn’t have a mitochondria. So where does the Krebs cycle occurs?? Thank you!
