#proximal convoluted tubule

6 public questions tagged with this topic.

Which part of nephron primarily reabsorbs water and solutes?

Correct option is C, Proximal tubule. In Excretory System, the accurate description is Proximal tubule, and that is what you should commit to memory. Keep the definition tight and the role clear — the functional job described in the stem is exactly what Proximal tubule does in Excretory System. Then Proximal tubule is the answer you can defend. Check yourself by covering the options and writing the answer first, then matching the letter — that builds confidence. If the wording feels dense, translate it into everyday language first, then map that plain sentence back onto Proximal tubule. Remember that physiology questions reward precise language: name the process, the location, and the outcome, then match that to the option text.

Na⁺–H⁺ antiporter in PCT is important for reabsorption of:

Pick B: Bicarbonate. Thinking about Excretory System in a practical way — what the structure does, or what the process achieves — leads you here. Clinically and academically, the same logic shows up again and again: Bicarbonate is the option that correctly names the structure, process, or principle asked for in Excretory System. Hence Bicarbonate is correct. Treat this as a building block for the rest of Excretory System; neighbouring topics often reuse the same principle. Keep a one-line summary card for this idea and revisit it before the paper; short, repeated review beats long cramming sessions. If the wording feels dense, translate it into everyday language first, then map that plain sentence back onto Bicarbonate.

Na⁺–glucose symporter is located on which membrane of PCT cells?

Pick B: Apical. Thinking about Excretory System in a practical way — what the structure does, or what the process achieves — leads you here. Clinically and academically, the same logic shows up again and again: location matters here: Apical is the structure or site that matches the description. Hence Apical is correct. Treat this as a building block for the rest of Excretory System; neighbouring topics often reuse the same principle. Keep a one-line summary card for this idea and revisit it before the paper; short, repeated review beats long cramming sessions. If the wording feels dense, translate it into everyday language first, then map that plain sentence back onto Apical.

Glucose reabsorption in PCT occurs mainly via:

Go with C — Secondary active transport. Within Excretory System, that statement lines up with the standard definition and the usual exam wording you’ll see. In plain terms, the functional job described in the stem is exactly what Secondary active transport does in Excretory System. Holding that picture in mind makes Secondary active transport feel natural rather than something you only memorise. Link the term to a real body example (organ, tissue, or ion flow) so the idea stays concrete under exam pressure. A short mental diagram helps — start from stimulus or structure, follow the pathway, and stop at the functional result described by Secondary active transport.
