What is glycolysis?
  1. The additive used to preserve glucose in blood.
  2. The destruction of red blood cells.
  3. The process of breaking down glucose for energy.
Explanation
Answer: C - Glycolysis is the action of breaking down glucose for energy. In blood, RBC’s and WBC’s use glucose for energy. This natural occurring action can cause inaccurately lowered blood glucose and pH levels. Blood glucose levels are collected in specimen containers that contain an additive meant to prevent the breakdown of glucose (antiglycolytics). Specimens drawn for blood gas studies are transported to the laboratory immediately immersed in ice water, to slow the process.
