Intestinal epithelial cells pump glucose into the cell against its concentration gradient using the Na + – glucose symporter. Re

call that the Na + concentration is significantly higher outside the cell than inside the cell. The symporter couples the "downhill" transport of two Na + ions into the cell to the "uphill" transport of glucose into the cell. If the Na + concentration outside the cell ( [ Na + ] out ) is 159 mM and that inside the cell ( [ Na + ] in ) is 19.0 mM, and the cell potential is − 51.0 mV (inside negative), calculate the maximum energy available for pumping a mole of glucose into the cell. Assume the temperature is 37 °C.

Analysis of an unknown substance showed that it has a high boiling point and is brittle. It is an insulator as a solid but condu
DiKsa [7]

Answer:

The correct option is D (KBr)

Explanation:

Potassium bromide (KBr) is a typical example of an IONIC CRYSTAL. Positive and negative ions are arranged in a regular pattern to give a giant crystal lattice in an ionic solid.

Ionic crystals are hard and have high melting points because the electrostatic forces holding the ions are strong. In the solid state, ionic compounds are poor conductors of electricity because the ions are held rigidly in place and so cannot moves about.

When melted or when dissolved in water, the ions are free to move about and the ionic substances become good conductors of electricity.

Ionic crystals are also BRITTLE. When struck, they tend to shatter because as planes of ions slip by one another, they pass from a condition of mutual attraction to one of mutual repulsion.
