The reason why diet deficient in zinc does not reduce the number of red blood cells, but it impairs respiratory function by reducing CO 2 output. Concept introduction: The mineral zinc activates the enzymes of protein metabolism . It is a part of carbonate dehydratase and carbon dioxide transfer. It is important for the immune functions. Most carbonic anhydrase contains zinc ion in their functional site, and they are therefore classified as metalloenzymes.

Question

Below is the reaction catalyzed by carbonic anhydrase. Please answer the following questions. CO₂ + H₂O → H+ + HCO3* a. The forward reaction is favored in the lungs b. When protons decrease the pH [Select] [Select] c. CO₂ acts directly as a [Select] hemoglobin by reacting to form carbonic Answer 1: lungs Answer 2: decreases Answer 3: HbR Answer 4: negative heterotrophic state is favored Answer 5: and the allosteric effector of reacting to generate protons another allosteric effector that stabilizes the T state

Diabetic ketoacidosis is characterized by an increased level of ketone bodies, which causes metabolic acidosis. A patient in diabetic ketoacidosis will have an altered rate of ventilation. Will the patient be hyperventilating or hypoventilating? How will a change in the rate and depth of ventilation compensate for an acidosis that is metabolic in nature?

A patient accidentally swallows 4 pills of Ipecac, a known emetic. He then suffers the consequence, with one effect being hypochloremia. His blood gas results show an increased pCO2, increased pH, and increased bicarbonate levels as his body tries to correct the condition. Which of the following is the body's response to the condition stated above and as mirrored by the blood pH and gas analysis? metabolic correction of respiratory alkalosis metabolic correction of respiratory acidosis respiratory correction of metabolic alkalosis respiratory correction of metabolic acidosis
