The nephron reabsorbs glucose through a sodium/glucose transporter. What sort of transporter is it? A. Protein channel B. Antiporter C. Symporter D. Sodium pump
Understand the Problem
The question is asking for the type of transporter that the nephron uses to reabsorb glucose, specifically in relation to its mechanism of action with sodium. It requires knowledge of biological transport mechanisms.
Answer
Symporter
The nephron reabsorbs glucose through a sodium/glucose transporter. The correct type of transporter is a symporter.
Answer for screen readers
The nephron reabsorbs glucose through a sodium/glucose transporter. The correct type of transporter is a symporter.
More Information
A symporter transports two different molecules in the same direction across a cell membrane. In the nephron, glucose is reabsorbed along with sodium ions using this transport system.
Tips
A common mistake is confusing a symporter with an antiporter. Remember, a symporter moves substances in the same direction, whereas an antiporter moves them in opposite directions.
