Question

Which of the following is least likely to be present in glomerular filtrate (the filtrate produced by nephron before it enters the loop of Henle) of a healthy adult nephron?

• A. Amino acid
• B. Glucose
• C. Electrolytes
• D. Large molecular weight protein

Answer 1

The correct option is D Large molecular weight protein

Electrolytes, glucose, and amino acids are all filtered from the blood into the tubular filtrate, and subsequently reabsorbed. Large molecular weight protein are too large to pass through the glomerulus and into the tubular filtrate. So large molecular weight proteins are least likely to be present in the glomerular filtrate.
