Question

without oxygen, what is the only step of cell respiration that continues to happen? glycolysis calvin cycle etc krebs cycle

Explanation:

Cellular respiration has three main stages: glycolysis, the Krebs cycle (citric acid cycle), and the electron transport chain (ETC). Glycolysis occurs in the cytoplasm and does not require oxygen. The Krebs cycle and ETC are in the mitochondria and need oxygen. The Calvin cycle is part of photosynthesis, not respiration.

Answer:

Glycolysis
