Which among the following glucose transpoer present in beta cells ?
GLUT2 is the glucose transpoer present in the betacells and liver cells.It has a high Km for glucose.Hence entry of glucose is directly propoional to the glucose level.It is an insul;in independent transpo. GLUT3 is present in brain and GLUT4 medites insulin dependent transpo of glucose into muscle and adipose tissue. Ref: Murray R.K., Granner D.K. (2011). Chapter 40. Membranes: Structure & Function.
