Eukaryotic cells have a nucleus and Prokaryotic cells do not.
Answer – D. Facilitated diffusion through protein channels
Glucose molecules are too big to pass through the plasma membrane by direct diffusion, so Glucose gains entrance into a cell by facilitated diffusion through protein channels in the plasma membrane. Since glucose moves with the concentration gradient, the built-in protein channels are only there to facilitate the movement of glucose into the cell and no energy is expended.

Answer:
false
Explanation:
crustaceans are organisms like crabs and lobsters, while arachnids are organisms like spiders. To help me remember, I think of arachnophobia, which is the fear of spiders.
The correct answer is: sodium gradient
It is very important for glucose to be transported into proximal tubule cells (reabsorbed) because that is the way to prevent it from disappearing from the body through the urine.
Glucose is co-transported with sodium ions into the proximal tubule via the SGLT2 cotransporter. This cotransporter is an example of secondary transport because it uses the energy from downhill sodium ion gradient created by the ATPase pump to transport glucose.
