WebOct 29, 2024 · Can glycolysis occur without oxygen? Glycolysis requires no oxygen. It is an anaerobic type of respiration performed by all cells, including anaerobic cells that are killed by oxygen. For these reasons, glycolysis is believed to be one of the first types of cell respiration and a very ancient process, billions of years old. WebA) Glycolysis is widespread and is found in the domains Bacteria, Archaea, and Eukarya. B) Glycolysis neither uses nor needs O2. C) Glycolysis is found in all eukaryotic cells.

There are four basic steps of cellular respiration, glycolysis, pyruvate oxidation, Kreb's cycle, and the electron transport chain.

WebWithout fermentation, NAD+ levels would be depleted, and glycolysis could not continue. Fermentation occurs in the cytoplasm of cells, where glycolysis also takes place. This process is efficient in generating ATP under anaerobic conditions, but it is less efficient than cellular respiration, which requires oxygen. WebTherefore, without the presence of oxygen, glycolysis is the only process that can occur, and only two ATP molecules may be produced for each glucose molecule. When oxygen is present, pyruvate oxidation …
