Facilitated diffusion of glucose into a muscle cell Facilitated diffusion of glucose into a muscle cell A) Yes; sodium ion cotransport is required for facilitated diffusion of glucose.
B) No; sodium ion cotransport is required for simple diffusion of glucose, but not for facilitated diffusion of glucose.
C) No; sodium ion cotransport is required for active transport of glucose, but not for facilitated diffusion of glucose.

Option A.

Yes; sodium ion cotransport is required for facilitated diffusion of glucose.

Explanation:

Glucose is transported in the cell through facilitated diffussion because it is a large molecule and it will very difficult to be transported across the cell membrane through normal diffusion, so it is transported across the the concentration gradients.

sodium ion cotransport is required for facilitated diffusion of glucose because both glucose and sodium cannot be transported through simple diffussion so they pass through specific channels in the hydrophobic barrier formed by membrane proteins. Thereby crossing the membrane, the diffusion is facilitated by the channels but glucose and sodium must move against a concentration gradients tone transported.
