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.
How does oxygen affect the efficiency of cellular respiration?
Yes, it is less efficient because respiration gives us a yield of 36 ATP while during fermentation we only receive 2 ATP. So the less oxygen we can give the mitochondria the less energy we get in return. List the two processes that together result in cellular respiration.

Why does cellular respiration need oxygen?
Why Do We Need Oxygen For Cellular Respiration? Oxygen serves as a final electron acceptor of the electron transport chain in cellular respiration assisting the movement of electrons down a chain, resulting in the production of adenosine triphosphate (ATP). Oxygen combines with electrons and hydrogen ions to produce water. Hence the importance.

Oxygen is produced during cellular respiration and stored during photosynthesis. Carbon dioxide and water released by cellular respiration are used in photosynthesis. Photosynthesis releases the energy that is stored during the process of cellular respiration.
What is the role of oxygen in photosynthesis and in cellular respiration oxygen is used in photosynthesis to produce glucose and is released during cellular respiration?
Photosynthesis makes the glucose that is used in cellular respiration to make ATP. The glucose is then turned back into carbon dioxide, which is used in photosynthesis. While water is broken down to form oxygen during photosynthesis, in cellular respiration oxygen is combined with hydrogen to form water.
What is the role of oxygen in cellular respiration quizlet?
What is the role of oxygen in cellular respiration? Oxygen accepts high-energy electrons after they are stripped from glucose. Cellular respiration accomplishes two major processes: (1) it breaks glucose down into smaller molecules, and (2) it harvests the chemical energy released and stores it in ATP molecules.
How is oxygen used in cellular respiration?
How is oxygen used in cellular respiration? 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 happens to the oxygen that is used in cellular respiration?
During aerobic cellular respiration, glucose reacts with oxygen, forming ATP that can be used by the cell. Carbon dioxide and water are created as byproducts. The overall equation for aerobic cellular respiration is: In cellular respiration, glucose and oxygen react to form ATP.
What is the role of oxygen in photosynthesis?
Oxygen (O2) is evolved during photosynthetic electron transport when water is split by the oxygen-evolving complex to provide protons and electrons to the chloroplastic electron chain, thereby generating ATP and NADPH—the energy source and reducing power for plant metabolism.
What is the role of oxygen?
Oxygen plays a critical role in respiration, the energy-producing chemistry that drives the metabolisms of most living things. We humans, along with many other creatures, need oxygen in the air we breathe to stay alive. Oxygen is generated during photosynthesis by plants and many types of microbes.
Which statement best describes the role of oxygen in cellular respiration?
What best describes the role of molecular oxygen (O2) in aerobic respiration? It accepts electrons when reacting to form water.
What is the role of oxygen in photosynthesis?
Oxygen (O2) is evolved during photosynthetic electron transport when water is split by the oxygen-evolving complex to provide protons and electrons to the chloroplastic electron chain, thereby generating ATP and NADPH—the energy source and reducing power for plant metabolism.
What describes the roles of oxygen and water in photosynthesis and cellular respiration?
Photosynthesis converts carbon dioxide and water into oxygen and glucose. Glucose is used as food by the plant and oxygen is a by-product. Cellular respiration converts oxygen and glucose into water and carbon dioxide. Water and carbon dioxide are by- products and ATP is energy that is transformed from the process.
How is oxygen produced during photosynthesis?
During photosynthesis, plants take in carbon dioxide (CO2) and water (H2O) from the air and soil. Within the plant cell, the water is oxidized, meaning it loses electrons, while the carbon dioxide is reduced, meaning it gains electrons. This transforms the water into oxygen and the carbon dioxide into glucose.
Is oxygen a reactant of photosynthesis or cellular respiration?
