CHAPTER 2 What is a buffer?
What is a buffer? A buffer is a system of molecules and ions that acts to prevent changes in the H+ concentration, and thus serves to stabilize the pH of a solution.
CHAPTER 2 Describe the significance of this reaction in the blood: HCO3- + H+ H2CO3
Describe the significance of this reaction in the blood: The pH in blood is stabilized by HCO3- + H+ H2CO3 This is a buffering reaction for blood Addition of H+ drives the reaction to the right. (e.g. with lactic acid in the blood). Excessive vomiting (loss of H+) causes the reaction to go in the opposite direction
CHAPTER 2 Describe ketonuria: What is it? What causes it? (HINT: Clinical Application in edition 14 Fox).
KETONURIA “Clinical Application (p. 122) Ketone body production is increased during fasting and stringent diets, (or diabetes) resulting in ketosis (increased ketone bodies in the blood). Ketone bodies are excreted in the urine (ketonuria) For osmotic reasons, ketonuria is accompanied by excessive urinary water loss and dehydration.” Can also be caused by diabetes mellitus
