Answer 1

The citric acid cycle, it occurs without oxygen, and happens in the Mitochondrion. The next cycle occurs in the cell membrane, though.

Answer 2

Sorry - I wasn't paying attention to the notifications.

Answer 3

so would that make the answer Mitochondrion? or cell membrane?

Answer 4

Remember in the lesson, when it talked about the Electron Transmission Chain? That's the next stage.

Cellular Respiration (With oxygen), Krebs Cycle (Citric Acid Cycle; without oxygen), and ETC(Electron Transmission Chain).

Cellular Respiration = in cytoplasm
Krebs Cycle = in Mitochondria
Electron Chain = In Mitochondria Nucleus.
