GLUT4 is the glucose transporter involved in insulinstimulated glucose uptake into adipose tissue and skeletal muscle. The mechanism of glucose transport by GLUT4 is of which of the following types?

Question

Quizplus · Accepted Answer

GLUT4 facilitates the transport of glucose across cell membranes via facilitated diffusion, which is a passive transport mechanism that does not require energy. Facilitated diffusion is the spontaneous passage of molecules or ions across a biological membrane passing through specific integral transmembrane proteins. The glucose transporters, of which GLUT4 is a member, carry out sugar transport via the mechanism of facilitated diffusion.
