You place cells in a solution of glucose and measure the rate at which glucose enters the cells. As you increase the concentration of glucose solution, the rate at which glucose enters the cells increases. However when the glucose concentration of the solution is increased above 10M, the rate at which glucose enters no longer increases. Which of the following is the most likely mechanism for glucose transport in the cells?
A
Facilitated diffusion via a carrier protein
B
Facilitated diffusion without carrier protein
C
Active transport
D
Symport
Answer
Facilitated diffusion via a carrier protein
