Lactate Receptor Sites Link Neurotransmission
... Lactate, acting as a buffer between glycolysis and oxidative metabolism, is exchanged as a fuel between cells and tissues, depending on glycolytic and oxidative rates (Brooks 2009). The brain exports lactate at rest, but once blood lactate levels rise, for example, during physical exertion, there is ...
