A) ATP is the correct answer
The matching of each situation to the step in the urine formation process where the problem lies are as follows:
- Step 1: Stella's urine contains protein due to inadequate filtration.
- Step 2: High toxin levels in the blood are due to Secretion.
- Step 3: Increased Metabolic wastes are due to inadequate Reabsorption.
- Step 4: The presence of vital Vitamins in urine is due to inadequate Reabsorption.
Thus, Step 1 belongs to filtration, Step 2 belongs to secretion, and Steps 3 and 4 belong to reabsorption.
<h3>What is the important function of Nephron?</h3>
