Answer:
Aspartame is found in Nutra sweet which is a modified dipeptide rather than a carbohydrate and they are many times sweeter than monosaccharides galactose because they binds very tightly with the heterodimer GPCR receptors present on the tongue which is made up of proteins called taste receptor type 1 member 2 and taste receptor type 1 member 3.
This tight binding to aspartame generates a neuronal output that is sent to the brain and the brain interprets it as a super sweet compound. It's decrease off rate also contribute to its more sweetening effect.
Therefore the type of binding to taste receptors explains why aspartame is 500 times sweeter in human taste test.
The technology can help scientists study or look at cells, which in turn can let those scientists figure out if a cell is infected with a virus, or if it's a mutated cell that might cause a disease.
I need more t0 answer the qustion
Hey friend!
You stuck?
The organelle that sends out microtubules that connect to DNA during Metaphase are called centrioles. The connect to the DNA during metaphase, during that process they determine the position of the nucleus.
Hope this helps! :)
