Answer #1

1. Answer: Option B is correct
Explanation:
Reabsorption = Transfer of materials (liquids and solutes) from renal tubular lumen to the blood.

It occurs mainly in the proximal convoluted tubule. Most of the water, amino acids, glucose, and potassium are reabsorbed.

2. Answer: Option C is correct
Explanation:
Tubular secretion = Transfer of materials (liquids and solutes) from peritubular capillaries to the renal tubular lumen

Tubular secretion is mediated by both active transport and passive diffusion.
