1. Concentration ranges of ions in blood A. What is the upper and lower limit of concentrations in blood for H+, K+ and Na+? H+ Na+ K+ a. normal range: b. physiological range: B. What are the widths of the potential ranges that the respective ISEs would measure within the normal as well as physiological concentration ranges? Example: assume the normal range of Xion is from [Xa] to [Xb) - when we measure concentrations within this range with an ISE for X the values will be all within an x mV wide potential range H+ Na+ K+ a. normal range: b. physiological range: C. Which one of these 3 ions is the most tightly controlled ion in blood? The answer should be based only on the data provided. D. One mechanism of control of concentration is chemical buffering.
