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.
What is the primary role of oxygen in cellular respiration?
What is the primary 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 membrane during cellular respiration, they travel through the electron transport chain and eventually are accepted by oxygen to create water.
Does cellular respiration require oxygen?
Cellular respiration is the cellular process which transfers chemical energy from glucose to ATP. Oxygen is essential to have efficient cellular respiration; most organisms need oxygen for a single purpose: to release energy from food for use by cells. Explore further detail here.
Which stage of cellular respiration uses oxygen?
- Glycolysis
- Pyruvate oxidation
- Kreb’s Cycle (AKA Citric Acid Cycle)
- Oxidative phosporylation
How is oxygen used in cellular respiration?

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...
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.
Where does cellular respiration occur?
Glycolysis is the first step in cellular respiration, and it occurs in the main compartment of the cell: the cytoplasm. Cells let glucose in from the blood--the glucose comes from the food we eat. Next, cells convert glucose through several different compounds to make two ATP molecules and a molecule called pyruvate. A compound called NADH (nicotinamide adenine dinucleotide + hydrogen) is also created. This molecule stores electrons harvested from the glucose, which will be used later to create a larger amount of ATP.
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 do electrons move between proteins?
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.
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.
What is ATP used for?
A. ATP can be used by cells to drive endergonic reactions. B. ATP can be used to make RNA, which is an energy storage molecule in the cell. C. ATP synthesis is an exergonic reaction. D. ATP is required to generate the proton gradient in the intermembrane space of mitochondria.
Where is ATP made in eukaryotic cells?
How and where is ATP made in a eukaryotic cell? A. ATP is only made in the mitochondria in response to chemiosmosis. B. ATP is made in all compartments of the cell in response to endergonic reactions and is used to drive exergonic reactions in the cell.
Why does my cabin smell like hydrogen sulfide?
Unfortunately, when you turn on the water in the cabin you smell hydrogen sulfide (H2S) gas. After some research, you find out that the H2S may be due to the presence of sulfur bacteria living in your pipes.
Where is ATP made?
C. ATP can be made by direct phosphorylation of ADP in the cytoplasm, and by an enzyme complex that uses the energy from a proton gradient to drive ATP synthesis in the mitochondria. It can also be made in other locations in the cell, depending on the cell type.
Does glycolysis run in the presence of glucose?
In the presence of glucose, glycolysis will run to generate energy for the cell, but the Krebs cycle will be inhibited. B. Glycolysis will be inhibited, but the Krebs cycle will be functional, allowing it to be utilized to breakdown acetyl-CoA generated from beta-oxidation. C.
Is fat bad for the electron transport chain?
It is a bad idea, because consumption of fat is required to provide cofactors for the electron transport chain. C. It is a good idea, because under conditions where ATP levels are low in cells, carbohydrates will be stored, and fat stores will be catabolized via beta-oxidation to generate energy. D.
Is oxygen a cofactor?
No, oxygen is a required cofactor for the complexes in the electron transport chain. C . Yes, in the case that a cell can use a terminal electron acceptor other than oxygen, it can make use of the electron transport chain. D. No, oxygen is the primary electron acceptor in electron transport chains in all cell types .
