Which of the following are soluble compounds that contribute to intracellular osmolarity in shark tissues?

Question

Quizplus · Accepted Answer

Urea and trimethylamine oxide are soluble compounds that are found in high concentrations in the tissues of sharks to help maintain their internal osmotic balance. Glucose and amino acids may also contribute, but to a lesser extent. Excessively high levels of sodium and chloride would actually contribute to an increase in extracellular osmolarity and the need for the shark to regulate its internal balance. A proton pump is not a soluble compound and would not contribute to intracellular osmolarity.
