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.
What is the function of oxygen in cell respiration?
- Glycolysis: 2 ATP.
- Krebs Cycle: 2 ATP.
- Oxidative Phosphorylation (Electron Transport Chain/Chemiosmosis): 28 ATP.
- Fermentation: 2 ATP.

What happens to glucose and what is oxygen's role 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 oxygen's role in ATP production?
Thus, oxygen's role is to drive the entire set of ATP-producing reactions within the mitochondrion by accepting “spent” hydrogens. Oxygen is the final electron acceptor; no part of the process - from the Krebs Cycle through electron transport chain – can happen without oxygen.
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.
What's oxygen's role in the electron transport chain?
Oxygen is the terminal electron acceptor in the mitochondrial electron transport chain and therefore is required for the generation of energy through oxidative phosphorylation.
Why is oxygen O2 important to life?
Most living things need oxygen to survive. Oxygen helps organisms grow, reproduce, and turn food into energy. Humans get the oxygen they need by breathing through their nose and mouth into their lungs. Oxygen gives our cells the ability to break down food in order to get the energy we need to survive.
What is the role of oxygen in aerobic metabolism?
Aerobic metabolism uses oxygen as the final electron acceptor in the electron transport chain and combines with hydrogen to form water [1].
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.
Where does the oxygen used in cellular respiration end up?
the electron transport chainOxygen acts as a final electron acceptor in the electron transport chain, resulting in the formation of water. It drives the whole process leading to the formation of ATPs by oxidative phosphorylation.
What is oxygen's role in oxidative phosphorylation?
In oxidative phosphorylation, oxygen must be present to receive electrons from the protein complexes. This allows for more electrons and high energy molecules to be passed along, and maintains the hydrogen pumping that produces ATP.
Why is o2 a good final electron acceptor?

Why is oxygen important in the electron transport pathway and ATP synthesis?
Why is oxygen important in the electron transport pathway and ATP synthesis? Oxygen accepts electrons at the end of the electron transport chain to free the pathway for a new set of electrons.
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...
Where is oxygen used in cellular respiration?
In cellular respiration, oxygen is used in the inner mitochondrial membrane in the electron transport chain to facilitate oxidative phosphorylation.
What is the role of oxygen in cellular respiration?
The role of oxygen in cellular respiration is to act as the end electron acceptor. After electrons are dropped off at the inner mitochondrial membr...
What are the steps of cellular respiration?
Cellular respiration has three main steps: glycolysis, the citric acid cycle, and oxidative phosphorylation, where oxygen is used. Step 1: Glycolysis. Glycolysis is the first step in cellular respiration, and it occurs in the main compartment of the cell: the cytoplasm.
How to bring oxygen into the body?
Take a deep breath in and gently exhale. Every day, all day and all night, our lungs inhale and exhale air. Although calming, the goal of this process is to bring oxygen into the body.
What is the process of making ATP and carbon dioxide?
Cells in our body combine glucose and oxygen to make ATP and carbon dioxide. Cellular respiration starts with glycolysis, where glucose enters the cell, is converted to pyruvate, and makes a few ATP and NADH. Next, the pyruvate moves into the citric acid cycle, as acetyl Co-A and creates more ATP and NADH.
What is the molecule that transports electrons in the citric acid cycle?
The citric acid cycle also creates another molecule of ATP, additional NADH, and the molecule FADH (flavin adenine dinucleotide + hydrogen), which also transports electrons. The entire point of cellular respiration up until now has been to get a few ATP, but now it focuses on the electrons housed in the NADH.
What do cells use to make energy?
All body cells engage in cellular respiration. They use oxygen and glucose, a sugar found in the foods we eat and convert them to ATP (adenosine triphosphate), or cellular energy, and carbon dioxide.
How does ATP synthase work?
It has space for the hydrogen ions to flow into the mitochondria. As the hydrogen ions flow , ATP synthase harvests the energy stored and uses it to make ATP. Then, that energy can be used for all processes in the cells. Everything we do needs energy, which is ultimately made using oxygen and glucose.
How do proteins act?
The proteins act like factory workers, passing down the electrons in a chain. As the electrons pass through, four proteins use the energy stored in the electrons to move hydrogen ions into the intermembrane space. At the end of the chain is the ultimate electron acceptor: oxygen.
What is the role of oxygen in the ATP process?
In this role, oxygen is an electron acceptor within the electron transport chain which synthesizes ATP from nutrients. To complete the ATP synthesis process, however, a variety of additional enzymes, principally ATP synthase, must also be present.
What is oxygen used for?
Oxygen is used as an electron acceptor within the electron transport chain of aerobic respiration to generate adenosine triphosphate, or ATP. This compound is an essential component in intracellular energy transfer.
What is the process of anaerobic respiration?
Anaerobic respiration takes place when an organism converts nutrients into ATP without the presence of oxygen in the electron transport chain. Substances such as fumarate, nitrate, sulfate or sulfur are used instead. ADVERTISEMENT.
What is the difference between aerobic and anaerobic respiration?
Aerobic cellular respiration is in direct contrast of anaerobic respiration, which does not require oxygen. Cellular respiration, whether aerobic or anaerobic, is a metabolic process which converts nutrient energy into ATP and waste products. In the human body, this translates into breaking down food into energy stored as sugars and then using ...
