Best answer: Does cellular respiration recycle oxygen?

What happens to oxygen 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 is recycled in cellular respiration?

The four substances recycled during photosynthesis and respiration are carbon dioxide, water, oxygen and glucose.

Is oxygen oxidized or reduced in cellular respiration?

Cellular respiration is an oxidative process whereby an electron donor is oxidized and oxygen is reduced to produce carbon dioxide, water, and energy [3].

How is oxygen conserved in cellular respiration?

The AMOUNT of carbon-dioxide atoms released by respiration are EXACTLY EQUAL to the atoms of these materials contained in the oxygen and carbon converted. In this way respiration has conserved the mass or material and in this way followed the law of conservation of mass.

What would happen if oxygen were not available?

Explanation: Aerobic respiration requires oxygen. In aerobic respiration, one molecule of glucose is broken down to produce 34 to 36 molecules of ATP, the energy currency of the cell. If there was no oxygen available, aerobic respiration would stop and organsims that rely on aerobic respiration would die.

What substance is not recycled in cellular respiration?

Waste Products of Cellular Respiration

When pyruvate cannot be processed via the aerobic reactions of cellular respiration, either because not enough oxygen is present or the organism lacks the enzymes to make use of it, fermentation is one alternative.

What’s oxidized and reduced in cellular respiration?

During aerobic respiration, the oxygen taken in by a cell combines with glucose to produce energy in the form of Adenosine triphosphate (ATP), and the cell expels carbon dioxide and water. This is an oxidation reaction in which glucose is oxidized and oxygen is reduced.

How does cellular respiration follow the law of conservation of energy?

The law of conservation of energy states that energy can never be created nor destroyed. … Cellular respiration uses the glucose and oxygen gas to produce water, carbon dioxide, and a usable form of energy known as ATP (which stands for adenosine triphosphate).

How is matter conserved during cellular respiration?

In cellular respiration, complex molecules containing carbon react with oxygen to produce carbon dioxide and other materials. … Matter is conserved during cellular respiration because atoms are conserved in physical and chemical processes.
