What is the oxygen used for in cellular respiration?
In cellular respiration, oxygen is used in the cells to produce energy. During this process, cells in our body use oxygen to produce ATP- the energy currency of the cell from glucose.
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 happens if oxygen is absent in cellular respiration?
When oxygen is not present and cellular respiration cannot take place, a special anaerobic respiration called fermentation occurs. Fermentation starts with glycolysis to capture some of the energy stored in glucose into ATP.
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 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 main product of cellular respiration?
The main product of any cellular respiration is the molecule adenosine triphosphate (ATP). This molecule stores the energy released during respiration and allows the cell to transfer this energy to various parts of the cell. ATP is used by a number of cellular components as a source of energy.
Which organelle is responsible for cellular respiration?
Eukaryotic organisms perform cellular respiration in their mitochondria – organelles that are designed to break down sugars and produce ATP very efficiently. Mitochondria are often called “the powerhouse of the cell” because they are able to produce so much ATP!
How many molecules of ATP are produced in a plant cell?
In fact, each molecule of sugar digested by a plant or animal cell yields 36 molecules of ATP! By comparison, fermentation usually only produces 2-4 molecules of ATP. Anaerobic respiration processes used by bacteria and archaebacteria yield smaller amounts of ATP, but they can take place without oxygen.
How does aerobic respiration work?
Instead of directly reducing intermediates of the Krebs cycle, aerobic respiration uses oxygen as the final electron receptor. But first, the electrons and protons bound to electron carriers (such as NADH), are processed through the electron transport chain. This chain of proteins within the mitochondrial membrane uses the energy from these electrons to pump protons to one side of the membrane. This creates an electromotive force, which is utilized by the protein complex ATP synthase phosphorylate a large number of ATD molecules, creating ATP.
Why is ATP not used for long term energy storage?
Because ATP is not stable over long periods of time, it is not used for long-term energy storage. Instead, sugars and fats are used as a long-term form of storage, and cells must constantly process those molecules to produce new ATP. This is the process of respiration. The process of aerobic respiration produces a huge amount ...
What is the process of converting sugars into energy?
Cellular respiration is the process through which cells convert sugars into energy. To create ATP and other forms of energy to power cellular reactions, cells require fuel and an electron acceptor which drives the chemical process of turning energy into a useable form.
Why is NAD+ important in fermentation?
This is helpful to the cell because NAD+ is necessary for glycolysis. In the case of alcoholic fermentation, pyruvic acid undergoes an additional step in which it loses an atom of carbon in the form of CO 2. The resulting intermediate molecule, called acetaldehyde, is then reduced to produce NAD+ plus ethyl alcohol.
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 ...
What is the role of oxygen in aerobic respiration?
The major role of oxygen in aerobic respiration is to synthesize the energy currency of the cell ATP by accepting electrons generated from the breakdown of the macromolecules present in the food. It can also be said that oxygen is essential for the breakdown of the macromolecules present in the food we ingest.
