what molecules are reabsorbed by tubular reabsorption?
450263
Sodium/proton exchanger, which enables reabsorption of bicarbonate. Glucose, amino acids and other substances diffuse out of the epithelial cell down their concentration gradients on passive transporters and are then reabsorbed by the blood capillaries.
616903
Potassium ion, sodium chloride, calcium ion, amino acids, glucose, bicarbonate ion and water are reabsorbed back into the blood stream. Any filtered amino acids and glucose are also reabsorbed back into the blood stream. Hydrogen ions, uric acid and drugs are secreted from the blood into the proximal convoluted tubule.
941536
Creatinine is removed from the blood chiefly by the kidneys, primarily by glomerular filtration, but also by proximal tubular secretion. Little or no tubular reabsorption of creatinine occurs. If the filtration in the kidney is deficient, blood creatinine concentrations rise.
578456
When the filtrate leaves the Bowman's capsule and enters the proximal convoluted tubule, sodium and chloride ions, as well as amino acids, glucose and vitamins move back into the blood. This occurs by them diffusing from the filtrate into the cells lining the proximal convoluted tubule.
26803
By the time the filtrate has reached the mid part of the proximal tubule, 100% of the filtered glucose and amino acids have been reabsorbed, and large amounts of sodium, bicarbonate, phosphate, lactate, and citrate ions.

Once the filtrate passes through the thick ascending limb of Henle, it enters the distal convoluted tubule, which is a duct of the renal tubule located in the kidney's cortex that reabsorbs calcium, sodium, and chloride and regulates the pH of urine by secreting protons and absorbing bicarbonate.

ADH increases the permeability to water of the distal convoluted tubule and collecting duct, which are normally impermeable to water. This effect causes increased water reabsorption and retention and decreases the volume of urine produced relative to its ion content.

Reabsorption includes passive diffusion, active transport, and cotransport. Water is mostly reabsorbed by the cotransport of glucose and sodium. Filtrate osmolarity changes drastically throughout the nephron as varying amounts of the components of filtrate are reabsorbed in the different parts of the nephron.

The loop has a sharp bend in the renal medulla going from descending to ascending thin limb. The thin ascending limb is impermeable to water, but it is permeable to ions. Sodium (Na+), potassium (K+) and chloride (Cl−) ions are reabsorbed from the urine by secondary active transport by a Na-K-Cl cotransporter (NKCC2).
1133726
The liquid entering the loop of Henle is the solution of salt, urea, and other substances passed along by the proximal convoluted tubule, from which most of the dissolved components needed by the body—particularly glucose, amino acids, and sodium bicarbonate—have been reabsorbed into the blood.

So a second process, called reabsorption, moves essential materials from the nephron back into the blood. Reabsorption occurs when transport proteins molecules in the walls of the nephron return essential substances such as glucose, amino acids, water, and salt to the capillaries that surround the nephron.

Sodium is actively pumped out, while potassium and chloride diffuse down their electrochemical gradients through channels in the tubule wall and into the bloodstream. The walls of the thick ascending limb are impermeable to water, so in this section of the nephron water is not reabsorbed along with sodium.

The electrons passing through the electron transport chain gradually lose energy, High-energy electrons donated to the chain by either NADH or FADH2 complete the chain, as low-energy electrons reduce oxygen molecules and form water. ... The end products of the electron transport chain are water and ATP.

C. So a second process, called reabsorption, moves essential materials from the nephron back into the blood. Reabsorption occurs when transport proteins molecules in the walls of the nephron return essential substances such as glucose, amino acids, water, and salt to the capillaries that surround the nephron.
