Oxygen and Carbon Dioxide

  • Oxygen is taken up by the haemoglobin in red blood cells to be used for cellular respiration
  • Carbon dioxide is taken up by plasma in the blood and taken back to the lungs to be exhaled
  • Carbon Dioxide is a waste product of cellular respiration

What cell contains hermoglobin molecules?

in red blood cells. and it is hemoglobin. dat is the US spelling. for UK, it will b haemoglobin


In what location do the RBC shed the oxygen molecules?

Red blood cells release oxygen molecules in the capillaries of body tissues where they are needed for cellular respiration. The oxygen diffuses from the red blood cells into the surrounding tissues due to the concentration gradient between the red blood cells and the tissues.


What part of the circulatory system carries oxygen to the cells?

The red blood cells in the blood carry oxygen to the cells. The oxygen is bound to hemoglobin, a protein in the red blood cells, and is transported throughout the body via the circulatory system.


Would osmosis have a higher concentration of water molecules distilled water or red blood cells?

Distilled water would have a higher concentration of water molecules compared to red blood cells. Red blood cells have solutes dissolved in them, so they have a lower concentration of water molecules relative to distilled water. This concentration gradient would result in osmosis moving water into the red blood cells to equalize the concentrations.


What molecules in red blood cells contains the oxygen?

The hemoglobin molecule in red blood cells are responsible for transporting oxygen.


Where does blood get oxygen from?

Capillaries in your lungs provide oxygen to the haemoglobin molecules of red blood cells.


What is the content of human red blood cells?

Red blood cells are packed with a chemical compound called hemoglobin, which has the ability to both absorb and release oxygen molecules.


Where do the red cells drop the oxygen off?

Red blood cells drop off oxygen to tissues and cells in the body through the process of diffusion in capillaries. Oxygen molecules bind to hemoglobin in red blood cells in the lungs and are released when the red blood cells reach tissues with lower oxygen concentration.


Mature red blood cells in the circulating blood are filled with what?

Mature red blood cells in the circulating blood are filled with hemoglobin, a protein that carries oxygen from the lungs to all parts of the body.


What are the characteristics of mature red blood cells?

LOTS of haemoglobin (Hb) molecules to carry oxygen. (ie. ~100 million Hb/red blood cell). Immature red blood cells have few Hb in each blood cell.


What are the cells in blood that carry oxygen?

Red blood cells, also known as erythrocytes, are the cells in blood that carry oxygen. They contain hemoglobin, a protein that binds to oxygen molecules in the lungs and releases them to tissues throughout the body.
