True regarding transpo across a cell membrane is :: (A) Cl- with glucose sympo, (B) Na+ with glucose anteprot, (C) Na+ with glucose sympo, (D) K+ with glucose sympo
Answer is C. C i.e. Na+ with glucose sympo In this along with Na+, another substance is carried by the carrier protein called sympo. The energy is obtained from diffusion process of Na+ due to concentration gradient across the cell membrane.
