<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

Concentration cell based on the Ni2 -Ni cell reaction.
Alex73 [517]

Answer:

Explanation:

The missing diagram contained in this question is first attached in the image below.

The objective of this question is to determine how ions migrate when the cells are operating by assuming the solutions are composed of Ni(NO3)2.

From the information provided:

In this instance, the ions tend to move first from cathode to anode in terms of raising the concentration of Ni(2+) at the anode, resulting in the development of a dead cell. The initial concentration of [Ni(2+)] in the anode solution is 1.00 × 10⁻³ M, which gradually increases to 0.5 M, during which both the cathode and the anode possess the same concentration at the same point.

This causes Q(equilibrium constant) to equal  1 as well as log(Q) to equal 0, indicating that the cell is dead.

As a result, the cell will cease to operate, and nothing will migrate from the left to the right side.
