B
Glycolysis
C
Electron Transport Chain
D
Oxidative Phosphorylation
Verified step by step guidance1
Understand the process of cellular respiration, which consists of several stages: Glycolysis, Krebs Cycle, Electron Transport Chain, and Oxidative Phosphorylation.
Recognize that cellular respiration can be divided into aerobic and anaerobic processes. Aerobic processes require oxygen, while anaerobic processes do not.
Identify Glycolysis as the first step in cellular respiration, which occurs in the cytoplasm and does not require oxygen, making it an anaerobic process.
Note that the Krebs Cycle, Electron Transport Chain, and Oxidative Phosphorylation are aerobic processes that occur in the mitochondria and require oxygen.
Conclude that Glycolysis is the step of the cellular respiration pathway that can take place in the absence of oxygen, allowing cells to generate energy anaerobically.
