2. a. At what rate does glucose enter a cell by passive diffusion alone? Estimate a typical cell as an ideal sphere with a diameter of 20 ?m. Remember that the surface area of a cell is 4?r2. The permeability coefficient (P=KD/x) for glucose is 3×10-8 cm/sec. For normal, steady-state […]

The normal pH range for systemic arterial blood is between 7.35 and 7.45. Any levels that drop below a pH of 7.35 is a condition known as acidosis. Any levels that rise above a pH of 7.45 is known as alkalosis. Acidosis can depress the central nervous system, which if […]
