<h2>Urea </h2>

Explanation:

Urea is a small nitrogenous compound which is the main end product of protein catabolism in mammals

  • Urea is a nitrogen-containing substance normally cleared from the blood by the kidney into the urine
  • It is made predominantly in the liver from ammonia and bicarbonate and is one of the main components of urine
  • The rate of synthesis varies from 300 to 600 mmol/day depending on the protein intake
  • All of this urea eventually finds its way into the urine
  • Because urea makes up a large part of the obligatory solute excretion, its osmotic pressure requires significant volumes of water to carry the urea
  • Urea passively crosses biological membranes, but its permeability is low because of its low solubility in the lipid bilayer
  • Some cells speed up this process through urea transporters, which move urea by facilitated diffusion
  • Urea is passively reabsorbed in the proximal tubule, but its route of transport is not clear
  • Urea transporters have not yet been identified for the proximal tubule

I think the answer is glucose + fructose - sucrose. If yes, then how to justify the answer.
SVEN [57.7K]

Answer: Your guess is right

Explanation: Other reactions release energy, so forming sucrose from glucose and fructose is endoergic. Also a water molecule is formed.

When two molecules form new molecule, order is increased and energy is needed that. IT could also possible to use standard energies of formation.
