In a hypothetical study, cells are placed in a solution of glucose in which the concentration of glucose is
gradually increased. At first, the rate at which glucose enters the cells is found to increase as the
concentration of the glucose solution is increased. But when the glucose concentration of the solution
is increased above 10 M, the rate no longer increases. Which of the following is the likely mechanism
for glucose transport into these cells?
Оа
Ob
Ос
Od
Tertiary active transport
Facilitated diffusion via a carrier protein
Facilitated diffusion via a channel protein
Pinocytosis

Respuesta :

The most likely mechanism for glucose transport into these cells is facilitated diffusion via carrier proteins.  This mechanism does not require energy.

Facilitated diffusion and cellular transport

Facilitated diffusion is a mechanism used by cells to transport substances in favor of a concentration gradient.

In facilitated diffusion, substances are transported across a semipermeable barrier from a region of high concentration to a region of low concentration.

Facilitated diffusion does not require energy to transport substances and make use of specific transporter protein called carriers.
