Students in Anatomy and Physiology learn the structure and function of the body’s organ systems (digestive, respiratory, cardiovascular, nervous, etc.). Students dissect animal specimens and analyze ...

Separate from this process, pyruvate, without oxygen, accepts the hydrogen ions generated from ATP’s conversion to ADP and becomes lactate, not lactic acid, helping reduce acidity.

Here I discuss the 'fast' actions of ATP at synapses, the properties of the receptors that are activated by ATP and the physiology of ATP signalling, with emphasis on its role in pain processing.

The vacuolar (V-)ATPases are ATP-driven proton pumps that function to acidify intracellular compartments and transport protons across the plasma membrane. They function in various normal and ...
