Adipose tissue and skeletal muscle
Which glucose transporter is low in adult muscle?
GLUT-1
What is the effect of insulin on GLUT-4 transporters?
Increases the number of active transporters

GLUT-1
Study Notes
Glucose Transporters
- GLUT-3 is primarily found in neurons.
Tissue Distribution
- GLUT-1 is abundant in brain, kidney, and placenta.
- GLUT-4 is abundant in adipose tissue and skeletal muscle.
GLUT-4 Regulation
- Insulin stimulates the translocation of GLUT-4 to the plasma membrane, increasing glucose uptake.
Glucose Transporter Distribution
- GLUT-4 is low in adult muscle.
- Not all glucose transporters have the same distribution in tissues.
- GLUT-1 is the most abundant in erythrocytes.
