Q1 · Membrane Transport
NEET PGEasyExplanation
The Na+/K+ ATPase extrudes three sodium ions and imports two potassium ions per ATP hydrolysed, making it electrogenic. It maintains the resting membrane potential and cell volume.
Q2 · Body Fluid Compartments
NEET PGMediumExplanation
Total body water is about 60% of body weight, or 42 litres. Two-thirds is intracellular, around 28 litres, and one-third extracellular, around 14 litres, of which plasma is about 3 litres and interstitial fluid about 11 litres.
Q3 · Resting Membrane Potential
MediumExplanation
The resting membrane is most permeable to potassium, so the resting potential of about -70 mV lies close to the potassium equilibrium potential predicted by the Nernst equation.
Q4 · Oncotic Pressure
EasyExplanation
Albumin is the most abundant plasma protein and, being smallest, contributes 75 to 80% of plasma oncotic pressure. Hypoalbuminaemia reduces oncotic pressure and causes oedema.
Q5 · Transport Mechanisms
HardExplanation
Intestinal glucose uptake uses the sodium-glucose cotransporter SGLT1, a secondary active transport that harnesses the sodium gradient set up by the Na+/K+ ATPase. GLUT2 then moves glucose out basolaterally.
General Physiology sits within Physiology, which carries the same syllabus in both exams. This set runs to 5 questions, each tagged Easy, Medium or Hard, 1 of them at Hard, and 2 drawn from previous-year papers.
Answer first, then read the explanation even on the ones you got right — the reasoning is where General Physiology marks are actually won, and it is what separates a recalled fact from a question you can solve in a new form. Once the Easy set feels comfortable, filter to Hard to find the gaps Physiology examiners keep returning to.
FAQ
Yes. Every question and explanation in this General Physiology set is free and open — no login, no form and no payment. The explanation appears the moment you answer.
General Physiology sits within Physiology, which appears in the same form in both syllabuses. System-wise physiology with the mechanisms examiners test most: cardiac and respiratory regulation, renal handling, endocrine axes and nerve conduction.
