What are the relative concentrations of Na⁺, K⁺ and dissolved proteins in the intracellular solution (i.e. cytosol) as opposed to in the extracellular fluid? A) $\uparrow$ Na⁺, $\uparrow$ K⁺, and $\uparrow$ dissolved proteins inside the cell B) $\uparrow$ Na⁺, $\downarrow$ K⁺, and $\uparrow$ dissolved proteins inside the cell C) $\downarrow$ Na⁺, $\uparrow$ K⁺, and $\uparrow$ dissolved proteins inside the cell D) $\downarrow$ Na⁺, $\downarrow$ K⁺, and $\downarrow$ dissolved proteins inside the cell

Na+ and K+ are both cations that need to be in specific concentrations for proper intracellular function. The cytosol typically has a higher concentration of K+ compared to Na+, whereas the extracellular solution has a higher concentration of Na+ compared to K+. Therefore, Na⁺ would be relatively lower in concentration in the intracellular solution compared to the extracellular fluid, whereas K⁺ would be relatively higher in concentration in the intracellular solution. Dissolved proteins are also typically found in higher concentrations in the intracellular solution compared to the extracellular fluid.
