The Energetics of Coupled Transport Guccos concentration is higher in the geoplasm than in the extracelular envionment. Nat conceotration is higher is the extracelulsr environment than in the cheplasm. Animal cells can take up glucose egainst its concentration gradient using a Natiglucose symportes. indicate if the following statemeats are true or ts se. A. in the Na + iglucose symportec Na + is alse moving agaist its concentrason gredient B. For the symporter to woek, the cell inust fist eslablihh a Na 4 concentration gradient C. A symporter works by making the phospholpa biayer more permeable to lons and glucose Iicirk fosing M D. Moving glucose sganst its concentration gredient is a form of active tranport. C. A Na'/gucose entiporter woudd be capable of moving glucese into the cell while meving tis + out of the cell. H. Since the Na"iglucote symporter exchanges a singe glucose for a single Na , it can also be considered a unportec. .
