Hexokinase is a family of four enzymes including glucokinase, also called hexokinase IV in liver and pancreatic islet cells.

Where is hexokinase found in cell?

It is the hexokinase found in muscle and heart. Hexokinase II is also located at the mitochondria outer membrane so it can have direct access to ATP. The relative specific activity of hexokinase II increases with pH at least in a pH range from 6.9 to 8.5.

Is hexokinase in muscle cells?

Two isoforms of hexokinase (type I and type II) are expressed in skeletal muscle; however, the intracellular distribution of these hexokinase isoforms in human skeletal muscle is unclear.
