alleryGlomerular filtration in the kidney is driven by
Aactive transport using ATP
Bblood pressure forcing plasma through capillary walls
Cdiffusion only
Dosmosis only
Answer & Solution
Correct answer: B. blood pressure forcing plasma through capillary walls
Filtration is passive — driven by blood hydrostatic pressure in the glomerulus.
Plasma (minus large proteins) gets forced into Bowman's capsule.
Reabsorption and secretion in later parts of the nephron use ATP.
