Question 27

Measurements in a tissue show that the glucose concentration is 5.0 mmol dm−35.0\,\mathrm{mmol\,dm^{-3}}5.0mmoldm−3 in the blood supplying the cells and 1.0 mmol dm−31.0\,\mathrm{mmol\,dm^{-3}}1.0mmoldm−3 inside the cells.

The cells begin to respire at a faster rate.

Explain how this affects the movement of glucose from the blood into the cells.
