A glucose transporter changes shape when it binds to a molecule of glucose. The shape change moves glucose down its concentration gradient to the opposite side of the membrane, where it detaches from the transport protein. What does this illustrate?
A) facilitated diffusion
B) endocytosis
C) active transport
D) exocytosis
E) osmosis
Facilitated Diffusion
Passive transport mechanism in which a solute follows its concentration gradient across a membrane by moving through a transport protein.
Concentration Gradient
A variation in the concentration of a substance across a distance.
Glucose Transporter
Proteins located in cell membranes that assist in the transport of glucose molecules into and out of cells, facilitating the use of glucose for energy.
