Question

Which of the following is FALSE concerning glucose transport across the proximal tubule?

1) Glucose is normally 100
2) Glucose is actively transported across the apical membrane by cotransport with sodium.
3) Glucose is passively transported across the basolateral membrane by facilitated diffusion.
4) Glucose transport requires energy.
5) Glucose moves by paracellular transport.

Answer 1

The false statement concerning glucose transport across the proximal tubule is that glucose moves by paracellular transport.

Step-by-step explanation:

The false statement concerning glucose transport across the proximal tubule is 5) Glucose moves by paracellular transport.

Glucose is normally reabsorbed from the filtrate in the proximal tubule. It is actively transported across the apical membrane by cotransport with sodium and then passively transported across the basolateral membrane by facilitated diffusion. This transport requires energy because it involves active transport and facilitated diffusion.
