Quantitative Assessment of Blood Lactate in Shock: Measure of Hypoxia or Beneficial Energy Source

Figure 8

Schematic diagram of a radial cross section of a resting skeletal muscle cell illustrating net lactate production and release to the blood from glycogen (Gly, crosshatched squares) and simultaneous net lactate uptake from the blood and oxidation by the mitochondria (Mit, crosshatched circles). The lactate concentration is indicated by the symbol . The simultaneous lactate uptake and release require that there are significant radial variations in the lactate cellular concentration adjacent to the plasma membrane.
