Why are proteins said to be transported rather than simply reabsorbed in the proximal convoluted tubule?
The process of hydrogen ion secretion in the proximal convoluted tubule occurs via which of the following mechanisms?
Choose from the following:
(A) hydrogen ions diffuse out of the glomerular filtrate of the proximal convoluted tubule, through extracellular fluid and into the peritubular blood
(B) carbon dioxide diffuses into the proximal convoluted tubule cell from peritubular capillary blood; undergoes a chemical reaction to form carbonic acid; dissociates into hydrogen and bicarbonate ions; the hydrogen ion diffuses into the glomerular filtrate of the proximal convoluted tubule
(C) hydrogen ions diffuse out of the peritubular capillary blood, through extracellular fluid and into the filtrate of the proximal convoluted tubule
(D) carbon dioxide diffuses into the proximal convoluted tubule cell from the glomerular filtrate; undergoes a chemical reacdtion to form carbonic acid; dissociates into hydrogen and bicarbonate ions; the hydrogen ions diffuse into the peritubular blood
Which of the following substances does NOT appear in normal filtrate within the distal
convoluted tubule?
Question options:
A) Sodium ions
C) Water
D) Glucose
