WebJan 26, 2024 · Glycolysis, which is the first step in all types of cellular respiration is anaerobic and does not require oxygen. If oxygen is present, the pathway will continue on to the Krebs cycle and oxidative phosphorylation. However, if oxygen is not present, some organisms can undergo fermentation to continually produce ATP. WebApr 21, 2024 · If oxygen is not present, the respiration cycle does not continue past the glycolysis stage. This type of respiration--without oxygen--is known as anaerobic respiration. Glycolysis occurs in both aerobic respiration and anaerobic respiration. During this stage, each glucose molecule splits in half, forming two molecules of pyruvate.
