What is the presence and absence of oxygen?

What is the presence and absence of oxygen?

Vocabulary. aerobic: In the presence of oxygen. aerobic respiration: Type of cellular respiration that requires oxygen. anaerobic: In the absence of oxygen.

Does glycolysis require the presence of oxygen?

Glycolysis requires no oxygen. It is an anaerobic type of respiration performed by all cells, including anaerobic cells that are killed by oxygen.

Why does cellular respiration stop after glycolysis when no oxygen is present?

If the Krebs cycle does not require oxygen, why does cellular respiration stop after glycolysis when no oxygen is present? When no oxygen is present, the final electron receptor is not available. As a result, the NADH produced in glycolysis and the Krebs cycle cannot be oxidized to NAD+.

What are the three stage of cellular respiration?

Cellular respiration occurs in three stages: glycolysis, the Krebs cycle, and electron transport. Glycolysis is an anaerobic process. The other two stages are aerobic processes. The products of cellular respiration are needed for photosynthesis, and vice versa.

What is the role of CO2 in cellular respiration?

During the process of cellular respiration, carbon dioxide is given off as a waste product. This carbon dioxide can be used by photosynthesizing cells to form new carbohydrates. Also in the process of cellular respiration, oxygen gas is required to serve as an acceptor of electrons.

Where does the CO2 from cellular respiration go?

The products of cellular respiration are carbon dioxide and water. Carbon dioxide is transported from your mitochondria out of your cell, to your red blood cells, and back to your lungs to be exhaled.

Do plants release carbon dioxide during cellular respiration?

The short answer is that when plants are doing cellular respiration, they produce carbon dioxide and water. When they are doing photosynthesis, they make oxygen and sugar.
