What is Which of the following DOES NOT depend on insulin for glucose uptake : and explain in detail?
Option a - Brain does not depend on insulin for glucose uptake Glucose uptake occurs in muscles (cardiac & skeletal) & adipose tissue GLUT-4 , which is insulin dependent. Only GLUT-4 is dependent on Insulin. In brain, GLUT-1 & GLUT-3 are present which are active during fasting state. Insulin always acts in a fed state.
