What else can I help you with?
Most toxic - urea NH3 NH4 or carbonic acid?
NH4 is most toxic, in fact in mammals it is always transported in the form of glutamate, because it is so toxic. So if this is in reference to humans, that is the most likely answer. NH3 on the other hand is non toxic unless present in high concentrations for whatever reason (such as problems with excretion when it is converted to Urea
Nitrogenous wastes such as ammonia, urea, and uric acid all result from?
the breakdown of proteins in the body. Ammonia is the most toxic waste product and is converted to urea in the liver for excretion. Urea is the main nitrogenous waste in mammals, while uric acid is prevalent in birds and reptiles.
What molecule is nitrogen found in?
Nitrogen is found in a number of molecules but perhaps most famously it is found in the DNA molecule.
Which is bigger molecule or cell?
A cell is typically larger than a molecule. Cells are the basic building blocks of living organisms and contain various molecules within them, such as proteins and DNA. Molecules are made up of atoms and can be very small in size compared to cells.
Is oxygen the most energy molecule?
Oxygen is not an energy molecule itself, but it is essential for the process of producing energy in our cells through cellular respiration. Glucose is a common energy molecule that is broken down with the help of oxygen to produce ATP, the primary energy currency of the cell.
What is the most toxic by-product of protein metabolism?
Ammonia is considered the most toxic by-product of protein metabolism. It is produced in the liver when amino acids are broken down and can be harmful if not properly excreted from the body.
What does the nitrogen cycle have to do with the most common reason why fish die?
The most common fish deaths are a result of ammonia or nitrite poisoning, in which the biological filtration has not been well established. The nitrogen cycle turns fish wastes to ammonia (which is toxic), then nitrite (still toxic), and finally, nitrate (not toxic in low concentrations).
What are the three nitrogenous waste excreted by animals?
The three nitrogenous wastes excreted by animals are ammonia (most toxic, released by aquatic animals), urea (less toxic, excreted by mammals), and uric acid (least toxic, excreted by birds and reptiles).
What is the form of nitrogenous waste that most fish give off?
Most fish excrete nitrogenous waste in the form of ammonia. Ammonia is highly toxic, but fish eliminate it primarily through the gills and some through the urine. Some fish species, particularly those living in environments with low water availability, convert ammonia to a less toxic form, such as urea or uric acid, before excreting it.
Special molecule that provides energy for a cells activities?
CH2O (glucose) is the most fundamental molecule metabolized by cells (in conjunction with Oxygen) for energy.
What is the most likely reaction between ammonia and a water molecule?
The most likely reaction between ammonia (NH3) and a water molecule (H2O) is the formation of ammonium hydroxide (NH4OH), also known as aqueous ammonia. This reaction involves the donation of a proton from water to ammonia, resulting in the formation of ammonium ion (NH4+) and hydroxide ion (OH-).
What type of refrigerant do air conditioners use and how toxic is it?
The types are: ammonia, sulfur dioxide, hydrocarbons like methane, methyl chloride, and methylene chloride, the freon and genetron and the water. The ammonia is the worst because can kill you, is the most toxic, the sulfur dioxide is corrosive and can injure plants but not to you, only is you breath it for a time, the hydrocarbons are not toxic like freon and genetron, and the water that is other refrigerant but is innocuous.
What is a molecule that is the most important for capturing and transferring free energy in cells?
ATP
List Three main nitrogenous wastes of animals what is the relative need for water?
The three main nitrogenous wastes in animals are ammonia, urea, and uric acid. Ammonia is the most toxic and soluble in water, requiring a high volume of water for its excretion. Urea is less toxic and requires a moderate amount of water for excretion. Uric acid is the least toxic and least soluble, needing very little water for excretion.
What is known as ammoniotelic organism?
Ammoniotelic organisms are those that excrete ammonia directly as their primary nitrogenous waste product. This method of excretion is typically found in aquatic animals, such as most bony fish and amphibian larvae, where ammonia can be readily diluted in water. Ammonia is highly toxic, so these organisms benefit from living in environments where they can efficiently eliminate it. This contrasts with ureotelic and uricotelic organisms, which convert ammonia into less toxic compounds like urea or uric acid for excretion.
Most toxic - urea NH3 NH4 or carbonic acid?
NH4 is most toxic, in fact in mammals it is always transported in the form of glutamate, because it is so toxic. So if this is in reference to humans, that is the most likely answer. NH3 on the other hand is non toxic unless present in high concentrations for whatever reason (such as problems with excretion when it is converted to Urea
Which animals excrete their nitrogenous waste entirely as ammonia?
Most aquatic animals, such as fish and marine invertebrates, excrete their nitrogenous waste mainly as ammonia. Ammonia is highly soluble in water and can be easily released through their gills or directly into the environment. This adaptation is beneficial in aquatic environments where water is readily available to dilute and remove toxic ammonia.
