I cannot found the exercise anywhere, so I will just explain how the toxin works.
A toxin is a toxic substance made by a living organism such as a bacterium, a fungus, a plant or an animal.
Labil toxins are toxins which are by easily degraded. among these toxins, there is the toxin of Escherichia coli and the cholera toxin of <span>Vibrio cholerea.

The intracellular target of cholera toxin is adenylate cyclase, one of the most important eukaryotic cell regulatory systems. This enzyme is involved in the conversion of ATP into a cyclic AMP (cAMP), a crucial intracellular messenger in a wide variety of cellular processes.
Cholera toxin catalyzes the transfer of ADP-ribose from NAD (Nicotinamide Adenine Dinucleotide) to a specific arginine residue of the Gsa protein, resulting in the activation of adenylate cyclase and consequently the increase of the intracellular level cAMP. AMPc activates a cAMP-dependent protein kinase, which leads to phosphorylation of the protein, modification of ion transport and finally diarrhea.

The maximum to minimum body water loss occurs by: Urine production, Skin losses, Lung respiration and minimum by Feces
<h3>What are the ways in which body loses water ?</h3>
Through breathing, sweating, and peeing, the body continuously loses water. You become dehydrated if you don't drink enough water or other liquids.
The majority of fluid loss happens through the stools, sweat, and urine, but it's not only those things. The quantity of body fluid lost daily through the skin, respiratory system, and water in the feces that cannot be readily measured is known as insensible fluid loss.
Physical exercise also influences increased respiratory water loss due to the increased expiratory volume and frequency of breathing. Various environmental elements like temperature, humidity, radiation, and atmospheric pressure mostly affect sweating and urine water loss.
