A mutated carrier protein has been embedded into the plasma membrane of an animal cell. The non-mutant version of this carrier protein is specific for glucose. However, glucose is unable to correctly bind to the mutant carrier protein in order to cross the plasma membrane and enter the cell.

Will glucose be able to cross the plasma membrane into the cell in another way?


Yes, through simple diffusion.


Yes, through osmosis.


No, glucose must bind to a carrier protein.


No, glucose can be made inside the cell and does not need to enter.
