What percentage of the oxygen carried from the lungs to the tissues is dissolved in plasma (the liquid, noncellular component of blood)?
A.2% to 3%
B.20% to 21%
C.15% to 18%
D.30% to 32%
Correct option : (A)2% to 3%
Oxygen is carried in the blood in two forms: (1) dissolved in plasma and RBC water (about 2% of the total) and (2) reversibly bound to hemoglobin (about 98% of the total).

2. What fraction of oxygen bound in the lungs is released in peripheral tissues for each hemoglobin? Which hemoglobin is better at transporting oxygen? Assume that the lung pO2 = 100 torr and that the peripheral tissue pO2 is 20 torr. Based on the shape of the saturation curve shown above, describe the effect of the Asp99Asn substitution on the cooperativity of oxygen binding? Is the cooperatively positively or negatively impacted by this mutation? 3. 4. In normal deoxyhemoglobin (hemoglobin...
3. The carbon dioxide produce in animal cells is transported to the lungs mostly dissolved in blood plasma. Essential to this process is the reaction of CO2 with water. Given the AHE= -612.96 kJ/mol for carbonic acid, calculate the AHreaction at 298.15 K. H2O(l) + CO2(g) 2 H2CO3(aq)
Dissolved Oxygen in Aquatic Ecosystems Dissolved oxygen is oxygen trapped in a fluid such as water. Since many living organisms require oxygen to survive, it is a necessary component of water systems such as streams, lakes, and rivers in order to support aquatic life. The dissolved oxygen is measured in units of ppm (parts per million). Examine the data in the table below, showing the amount of dissolved oxygen present and the number of fish observed in the body of...
Oxygen diffuses from blood into tissues because A. oxygen concentration in tissue is lower B. oxygen concentration in tissue is higher C. carbon dioxide concentration in tissue is higher D. carbon dioxide concentration in tissue is lower

(V) ( capillaries, (R) red blood cells, (W) white blood cells, (P) platelets, or (B) blood plasma. 1. back-flow valves carries dissolved carbon dioxide (CO2) and waste products for removal 3. carry blood away from heart 4. carry blood toward heart 5. cells that carry oxygen...
For the video response portion of this assignment, your job will be to state what would happen to the oxygen bond to Hemoglobin if the pH of the tissue was the same as that of the lungs using the logic of the person’s presentation you watched. Discuss whether or not you agree with this. The video said this: Oxygen must be transported in the blood from the lungs, because the partial pressure of oxygen (pO2) is relatively high (approximately 100...
1) Which of the following term describes the amount of air remaining in the lungs following a normal exhalation? a. Residual Volume b. Expiratory Reserve Volume c. Functional Residual Capacity d. Vital Capacity 2) Most gas exchange occurs a. at the alveoli b. in the primary bronchi c. in the trachea d. in the bronchioles 3) The content of inhaled air includes a. 78% oxygen; 21% nitrogen; .04% carbon dioxide b. 21% oxygen; 78% nitrogen; .04% carbon dioxide c. 21%...

The partial pressure of oxygen in the lung alveoli is a bit lower than in ambient air, being about 100 mm of mercury, or 0.13 Atm (it is lower than the partial pressure in air mainly because oxygen is continually taken up by the alveolar capillaries and carbon dioxide is continually released into the alveoli). In cell-free blood plasma (or a saline solution formulated to match key characteristics of blood plasma), which lacks red blood cells and therefore lacks hemoglobin,...
