Answer to Question 3. This gas is created when sugars are completely broken down into carbon molecules with oxygen molecules attached. Word Games What did you just call me?!

what is the definition of cell respiration

Thus, during cellular respiration one molecule of glucose, as well as oxygen, ADP, and free phosphate are catabolized to yield six molecules of carbon dioxide and an increase in usable energy in the form of eight molecules of ATP. What made you want to look up cellular respiration?

Cellular respiration

The process of aerobic respiration produces a huge amount of ATP from each molecule of sugar. In cellular respiration, glucose and oxygen react to form ATP. Term Meaning Cellular respiration The process by which organisms break down glucose into a form that the cell can use as energy ATP Adenosine triphosphate, the primary energy carrier in living things Mitochondria The eukaryotic cell structure where cellular respiration occurs Cytoplasm Jelly-like substance that fills the space between organelles Aerobic Process that requires oxygen Anaerobic Process that does not require oxygen Fermentation An anaerobic pathway for breaking down glucose.

The main carrier of energy in metabolism is the molecule ATP.

Because ATP is not stable over long periods of time, it is not used for long-term energy storage. This comment form is under antispam protection.

Plants undergo cellular respiration. Resources for cellular respiration Time Traveler! In the absence of oxygen, most eukaryotic cells can also perform different types of anaerobic respiration, such as lactic acid fermentation.

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.

Examples of different pathways for how sugars are broken down by organisms are illustrated below:. Nothing to see here.
