Oxygen is used as the end electron acceptor for the electron transport chain in cellular respiration. It allows electrons to be transferred through the electron transport chain in order to create an electrochemical gradient for hydrogen to create ATP.
What role does oxygen play in cellular respiration and photosynthesis?In photosynthesis, solar energy is harvested as chemical energy in a process that converts water and carbon dioxide to glucose. Oxygen is released as a byproduct. In cellular respiration, oxygen is used to break down glucose, releasing chemical energy and heat in the process.
What stage is oxygen used in cellular respiration?Cellular respiration has three main steps: glycolysis, the citric acid cycle, and oxidative phosphorylation, where oxygen is used. Glycolysis is the first step in cellular respiration, and it occurs in the main compartment of the cell: the cytoplasm.
