Which stage of cellular respiration is anaerobic?
A
Electron transport chain
B
Oxidative phosphorylation
C
Glycolysis
D
Citric acid cycle (Krebs cycle)
Verified step by step guidance1
Understand the concept of anaerobic processes: Anaerobic processes occur without the presence of oxygen. Cellular respiration includes both aerobic (oxygen-requiring) and anaerobic stages.
Review the stages of cellular respiration: Cellular respiration consists of glycolysis, the citric acid cycle (Krebs cycle), and oxidative phosphorylation (which includes the electron transport chain).
Analyze glycolysis: Glycolysis is the first stage of cellular respiration and occurs in the cytoplasm. It does not require oxygen, making it an anaerobic process. During glycolysis, glucose is broken down into two molecules of pyruvate, producing ATP and NADH.
Examine the other stages: The citric acid cycle (Krebs cycle) and oxidative phosphorylation (including the electron transport chain) occur in the mitochondria and require oxygen, making them aerobic processes.
Conclude that glycolysis is the anaerobic stage of cellular respiration, as it does not depend on oxygen to proceed.
