Final answer:
Glucose is transported via the GLUT carrier through passive transport, specifically by facilitated diffusion. It does not require energy like ATP and moves glucose from higher to lower concentrations.
Step-by-step explanation:
Glucose transported via the GLUT carrier is characterized as passive transport. This process is one where glucose uses a carrier protein in the cell membrane but does not require cellular energy, like ATP.
The GLUT transporter facilitates the movement of glucose by allowing it to move from an area of higher concentration to an area of lower concentration across the plasma membrane, termed facilitated diffusion. It is important to differentiate this from active transport, where substances are moved against their concentration gradient using energy, and co-transport (or secondary active transport), which involves the coupled movement of two substances across the membrane using a concentration gradient established by active transport of one of the substances.
