Hexokinase Type I functions in a mainly catabolic role; it is responsible for introducing glucose the glycolytic process in attempts to produce ATP. Hexokinase Type I phosphorylates a hexose into a hexose phosphate; most commonly the substrate of hexokinase I is found to be glucose and the product found to be glucose-6-phosphate. Mammalian brain tissue shows a high content of Hexokinase Type I which reiterates the idea that this isoenzyme is needed to maintain high rates of energy metabolism. Hexokinase Type I associated with brain homogenates demonstration an interaction with outer mitochondrial membrane. The binding of to this mitochondria is highly dependent on the N-terminus sequence. The protein porin is then responsible for the formation of a channel in which metabolites can pass through the mitochondrial membrame.
