The main substance re-absorbed into the blood in the nephron are glucose, electrolytes (sodium, potassium, chloride) and water.
Almost all the glucose is reabsorbed at the proximal tubule of the nephron. Sodium, potassium and chloride are reabsorbed at the ascending loop of Henle, and water is reabsorbed at the descending loop of Henle.
Other nutrients that are reabsorbed are magnesium, phosphates, carboxylate, bicarbonate, amino acids, some urea, proteins and oligopeptides.
Reabsorption occurs in two steps namely active or passive extraction of sustances from the fluid in the tubules of the nephron, and into the interstitium , then transport of these substances from interstitium and into the bloodstream.

The answer is letter D.) the components of a cell
Environmental science is an interdisciplinary field that studies the interactions of the environment. The component of a cell can be studied through the lens of biology and may not require addition disciplines.

Answer:
Adenosine triphosphate, also known as ATP, is a molecule that carries energy within cells. It is the main energy currency of the cell, and it is an end product of the processes of photophosphorylation (adding a phosphate group to a molecule using energy from light), cellular respiration, and fermentation.
It is made up of the molecule adenosine (which itself is made up of adenine and a ribose sugar) and three phosphate groups. It is soluble in water and has a high energy content due to having two phosphoanhydride bonds connecting the three phosphate groups
Its main function is to store energy within the cell. ... ATP hydrolysis is an exotermic reaction, releasing energy which is used by the cell.sphate groups.
