Substances that are cotransported into proximal convoluted tubule cells include A) urea with water. B) K⁺ with amino acids. C) amino acids with bicarbonate ions. D) glucose molecules with Na⁺. E) Cl⁻ with K⁺.

Question

Quizplus · Accepted Answer

In the proximal convoluted tubule of the kidney, glucose is reabsorbed alongside sodium ions through a process known as cotransport or symport. This mechanism involves the simultaneous transport of glucose molecules and Na+ ions into the cells, facilitated by specific cotransporter proteins in the cell membrane.
