Predict how water plays a role as a lubricant, reactant, coolant, and solvent during exercise

What will be an ideal response?


During exercise, water lubricates the joints for easy movement. It also functions in dehydration synthesis and hydrolysis reactions that occur during muscle contraction. Water also cools the body through the evaporation of perspiration from the skin. Water dissolves wastes generated by exercise.

Compartments A and B are separated by a membrane that is permeable to K+ but not to Na+ or Cl-. At time zero, a solution of KCl is poured into compartment A and an equally concentrated solution of NaCl is poured into compartment B. Which would be true once equilibrium is reached?

A. Diffusion of K+ from A to B will be greater than the diffusion of K+ from B to A. B. The electrical potential difference and diffusion potential due to the concentration gradient for K+ will be equal in magnitude and opposite in direction. C. The concentration of Cl- will be higher in B than it was at time zero. D. The concentration of Na+ in A will be higher than it was at time zero. E. There will be a potential difference across the membrane, with side B negative relative to side A.
