If a propyl group is added to the hydroxyl group on C1 of glucose, the modified glucose is unable to bind to its transporter on the extracellular surface. Another experiment showed that if a propyl group is added to the hydroxyl group on C6 of glucose, the modified glucose is unable to bind to its transporter on the cytosolic surface of the membrane. What observations are consistent with this mechanism of passive glucose transport?

Answer:

The passive transportation for the modification that occurs when a propyl group is added to the hydroxyl group on C1 of glucose will not occur

The passive transportation for the modification that occurs when a propyl group is added to the hydroxyl group on C6 of glucose will not occur

Explanation:

The hugeness of glucose poses a threat to its transportation across biological membrane as it can only be transported through Passive- mediated transport (when there is spontaneous transportation of molecules passively) and never through the regular diffusion.

The passive transportation for the modification that occurs when a propyl group is added to the hydroxyl group on C1 of glucose into the cell will not occur as the original C1 is one of the components responsible for extracellular surface binding.  

Also, the passive transportation for the modification that occurs when a propyl group is added to the hydroxyl group on C6 of glucose out of the cell will not occur as the original C6 is one of the components responsible for  cytosolic surface binding.
