  1. Diffusion and Osmosis problem set Download the problem set from MYSCNM (the main HUBI 5010 coursesite, Schmidt section). The problem set is a MS Word document with 15 questions. Answers are given at the end of that document. This file has a audio description of how to solve the first problem:

  2. Problem Fick's Law. J = PA(C1-C2) (questions 1 & 2) 1. During exercise, the concentration of oxygen in the blood returning to the lungs (C2) decreases two fold. The concentration of oxygen in the alveolar air spaces of the lungs is the same during exercise and while at rest. When using Fick's law to describe the movement of oxygen from the alveoli into the blood, which of C1, P and J is expected to increase during exercise?

  3. Solving question 1 Fick's Law. J = PA(C1-C2) In any question from Dr. Schmidt that requires you to apply Fick’s Law, the equation will be provided above the question. You need to know and understand the equation’s terms (J, P, A, C1, C2): J the rate of solute transfer across the membrane P thepermeability coefficient for the solute A the area of the membrane C1 C2concentrations of solute on the two sides of the membrane

  4. For this problem what is J? During exercise, the concentration of oxygen in the blood returning to the lungs (C2) decreases two fold. The concentration of oxygen in the alveolar air spaces of the lungs is the same during exercise and while at rest. When using Fick's law to describe the movement of oxygen from the alveoli into the blood, which of C1, P and J is expected to increase during exercise? Jis the rate of movement of oxygen from the air spaces in the lungs into the blood of the vasculature.

  5. For this problem what is C2? During exercise, the concentration of oxygen in the blood returning to the lungs (C2) decreases two fold. The concentration of oxygen in the alveolar air spaces of the lungs is the same during exercise and while at rest. When using Fick's law to describe the movement of oxygen from the alveoli into the blood, which of C1, P and J is expected to increase during exercise? C2 is the concentration of oxygen in the blood.

  6. For this problem what is C1? During exercise, the concentration of oxygen in the blood returning to the lungs (C2) decreases two fold. The concentration of oxygen in the alveolar air spaces of the lungs is the same during exercise and while at rest. When using Fick's law to describe the movement of oxygen from the alveoli into the blood, which of C1, P and J is expected to increase during exercise? C1 is the concentration of oxygen in the alveolar air spaces of the lungs.

  7. which of C1, P and J is expected to increase during exercise?a) Jb) C1c) P C1 is the concentration of oxygen in the alveolar air spaces of the lungs. During exercise, the concentration of oxygen in the blood returning to the lungs (C2) decreases two fold. The concentration of oxygen in the alveolar air spaces of the lungs is the same during exercise and while at rest. When using Fick's law to describe the movement of oxygen from the alveoli into the blood, which of C1, P and J is expected to increase during exercise?

  8. which of C1, P and J is expected to increase during exercise?a) Jb) C1c) P P isthepermeability coefficient for oxygen thepermeability coefficient for oxygen depends on the size of the oxygen molecule and the ease with which oxygen crosses cell membranes...these do not change during exercise!

  9. Solution question 1 which of C1, P and J is expected to increase during exercise?a) Jb) C1c) P During exercise, the concentration of oxygen in the blood returning to the lungs (C2) decreases two fold. Fick's Law. J = PA(C1-C2) Since C2 decreases, (C1-C2) will increase. The concentration gradient of oxygen from the alveolar air to the blood will increase. The rate of oxygen movement (J) will increase.
