Transport of Carbondioxide and Oxygen Quiz

What is the role of hemoglobin in the transport of oxygen in the blood?

• It releases carbon dioxide into the blood

• It binds to oxygen in the lungs and carries it to the body's tissues.

• It breaks down oxygen in the lungs

• It has no role in the transport of oxygen

Explain how hemoglobin acts as a carrier of oxygen in the body.

• Hemoglobin carries carbon dioxide to the lungs instead of oxygen

• Hemoglobin has no role in the transportation of oxygen in the body

• Hemoglobin binds to oxygen in the lungs and carries it to the body's tissues and organs.

• Hemoglobin breaks down oxygen in the lungs and releases it into the bloodstream

How do red blood cells contribute to the transport of oxygen in the body?

• They contain hemoglobin which binds to oxygen and carries it to the body's tissues.

• They have no role in transporting oxygen

• They produce carbon dioxide as a waste product

• They release oxygen into the bloodstream

Describe the role of red blood cells in the transportation of oxygen.

• Red blood cells transport oxygen to the body's tissues.

• Red blood cells produce oxygen for the body's tissues.

• Red blood cells store oxygen in the lungs.

• Red blood cells transport carbon dioxide to the body's tissues.

What is the mechanism of carbon dioxide transport in the blood?

• Dissolved in red blood cells

• Transported by white blood cells

• Stored in the liver

• Dissolved in plasma, chemically bound to hemoglobin, and as bicarbonate ions

Explain the process of carbon dioxide transport in the body.

• Carbon dioxide is transported through two main methods: dissolved in red blood cells and as free gas in the bloodstream.

• Carbon dioxide is transported through four main methods: dissolved in plasma, bound to red blood cells, as free gas in the lungs, and as bicarbonate ions.

• Carbon dioxide is transported through three main methods: dissolved in plasma, bound to hemoglobin, and as bicarbonate ions.

• Carbon dioxide is transported through three main methods: bound to plasma, dissolved in hemoglobin, and as bicarbonate ions.

What is the significance of the oxygen dissociation curve in the transport of oxygen?

• It measures the amount of carbon dioxide in the blood

• It shows the relationship between the partial pressure of oxygen and the saturation of hemoglobin.

• It determines the pH level of the blood

• It shows the relationship between blood pressure and heart rate

Describe the relationship between partial pressure of oxygen and hemoglobin saturation in the oxygen dissociation curve.

• As the partial pressure of oxygen increases, hemoglobin saturation decreases

• As the partial pressure of oxygen increases, hemoglobin saturation also increases until it reaches a plateau.

• Hemoglobin saturation increases as partial pressure of oxygen decreases

• There is no relationship between partial pressure of oxygen and hemoglobin saturation

How does the Bohr effect influence the transport of oxygen in the blood?

• The Bohr effect causes hemoglobin to release carbon dioxide instead of oxygen to tissues.

• The Bohr effect decreases hemoglobin's affinity for oxygen, promoting the release of oxygen to tissues.

• The Bohr effect has no impact on the transport of oxygen in the blood.

• The Bohr effect increases hemoglobin's affinity for oxygen, inhibiting the release of oxygen to tissues.

Explain the impact of pH and carbon dioxide on the Bohr effect in oxygen transport.

• High levels of carbon dioxide inhibit the release of oxygen from hemoglobin

• pH and carbon dioxide have no impact on the Bohr effect

• The Bohr effect is only influenced by temperature and pressure

• pH and carbon dioxide affect the Bohr effect by promoting the release of oxygen from hemoglobin in tissues with high carbon dioxide levels.
