A) Movement of potassium out of the cells in exchange for hydrogen into the cells.
B) Increased level of free calcium blocking sodium channels.
C) Increased glycolysis and utilization of phosphate.
D) Decreased cardiac contractility.
C) Increased glycolysis and utilization of phosphate.
Explanation: A) In metabolic alkalosis, there is increased glycolysis and utilization of phosphate. The movement of potassium out of the cells in exchange for hydrogen into the cells, increased level of free calcium blocking sodium channels, and decreased cardiac contractility are all associated with acidosis, not alkalosis.
