- You are studying with a friend who is describing the Bohr effect. She tells you that in the lungs, hemoglobin binds oxygen and releases hydrogen ion; as a result, the pH increases. She goes on to say that in actively metabolizing muscle tissue, hemoglobin releases oxygen and binds hydrogen ion and, as a result, the pH decreases. Do you agree with her reasoning? Why or why not?arrow_forwardWhich of the following occurs when erythrocytes are transferred from an isotonic solution to a hypertonic solution? Water leaves the cell and results to crenation. B Water leaves the cell and results to osmotic lysis. C) Water enters the cell and results to crenation. D Water enters the cell and results to plasmolysis.arrow_forwardOver the course of life, the diffusion capacity decreases by aboutA. 5 percent B. 10 percent C. 15 percent D. 20 percentarrow_forward
- Active tissues generate carbon dioxide, which diffuses out of the tissue into the bloodstream, to be carried away. Is this diffusion into the blood a case of flow up a gradient, or down? Explain.arrow_forwardHow much time would it take ATP to diffuse the following distances? (Use the equation for mean squared displacement in 1 dimension.) A. 1 µm (roughly the size of a bacterium) B. 6 µm (roughly the diameter of a T cell) C. 1 m (roughly the length of the axon of the sciatic nerve, which extends from the spinal cord to the big toe) D. Besides diffusion, what other mechanisms might a neuron use to transmit signals and transport molecules?arrow_forwardOxygen and carbon dioxide diffuse across our respiratory surface into and out of the blood via simple diffusion. The respiratory membrane is thin so gases diffuse only a short distance through the liquid and into the blood. Fluid buildup in the lungs increases the distance through the liquid medium. How does this impact the concentration of oxygen in the blood? Explain.arrow_forward
- The small capillaries in the lungs are in close contact with the alveoli. A red blood cell takes up oxygen during the 0.5 s that it squeezes through a capillary at the surface of an alveolus. What is the diffusion time for oxygen across the 1-μm -thick membrane separating air from blood? Assume that the diffusion coefficient for oxygen in tissue is 2×10−11m2/s. Give your answer to 1 significant figure.arrow_forwardWhich of the following statements is true about hemoglobin? a.hemoglobin b. Each hemoglobin molecule is made up of one alpha and one beta chain polypeptide. C. All that is needed to bind oxygen is a molecule of heme. D. Each hemoglobin molecule can carry four oxygen molecules.arrow_forwardInteractions between the cardiovascular and respiratory system provide oxygen to the body.a. Describe the path of blood through the heart, including arteries and veins. Start at the blood entering the heart from the body. Indicate when blood is oxygenated and deoxygenated.b. Oxygen is transported by hemoglobin. Describe how pH affects the deposition of oxygen in tissues c. What are two sources of oxygen stores in the body to allow for rapid use when undergoing physical exertion? d. Which chamber of the heart is the most muscular, and why?arrow_forward

Select one: a. Diffuse Side A to Side B. b. Diffuse Side B to Side A. c. No diffusion will occur; it is already at equilibrium.arrow_forwardVentilators are often used for individuals with COVID-19 to increase the rate of diffusion of gases across the alveoli. Ventilators could increase the rate of diffusion by impacting which factor of Fick’s law of membrane diffusion: a decreasing the diffusion coefficient (D) b decreasing surface area (A) c increasing the partial pressure difference (P1-P2) d increasing the diffusion distance e all of the abovearrow_forward8)After blood is “used” by cells, in other words they’ve taken the oxygen, where does it go? Select one: a. Back to the lungs for more oxygen b. Back to the heart and then on to the lungs for more oxygen c. Back to the heart to return to the body for more oxygen d. Back to the capillary beds for more oxygen e. Back to the brain, where the oxygen level is monitoredarrow_forward
