Max is curious about the protein content of his urine. Which of these statements provides an accurate basis for Tracey's response, explaining normal conditions
a. Few proteins are small enough to pass through the glomerular membrane, but the few that do are reabsorbed. So, proteins are not usually present in urine.
b. Most proteins pass through the glomerular membrane and are present in varying amounts in urine.
c. Most proteins pass through the glomerular membrane and are reabsorbed. So, proteins are not present in urine.
d. All proteins are negatively charged and too large to pass through the glomerular membrane. So, proteins are not normally present in urine.
