Verified
The active transport of substances into the filtrate is called tubular ________.
A) filtration
B) reabsorption
C) secretion
D) elimination
E) excretion
Tubular Secretion
Movement of materials, by means of active transport, from the blood into the filtrate of a nephron.
Active Transport
Carrier-mediated process that requires ATP and can move substances against a concentration gradient.
- Attain a comprehensive understanding of the urine generation process, including the critical phases of filtration, reabsorption, and secretion, alongside the influences on the glomerular filtration rate (GFR).
- Clarify how cellular and molecular dynamics contribute to the transport of materials across different segments of the nephron, focusing on active and passive strategies.

Final Answer :
C
Explanation :
Tubular secretion refers to the active transport of substances from the blood into the tubular fluid (filtrate) in the kidneys. This process helps in the elimination of waste products and the regulation of blood pH.
