Low selectivity of solute movement is a characteristic of A)salt pumping to control osmolarity. B)H⁺ pumping to control pH. C)reabsorption mechanisms along the proximal tubule. D)filtration from the glomerular capillaries. E)secretion along the distal tubule.

Question

Quizplus · Accepted Answer

Filtration from the glomerular capillaries is a passive process that occurs based on size and charge of the solute. This means that the selectivity of solute movement is low, as both small and large solutes can be filtered and there is no discrimination based on charge. In contrast, options A, B, C, and E all involve active transport mechanisms that are much more selective in terms of which solutes are moved across membranes.
