A 100 mm x 100 mm x 100 mm cell has a surface area that is _____ and a volume that is _____. when this volume is broken into man
Leno4ka [110]

Answer: 60,000 mm2; 1,000,000 mm3; larger

The cell has the same length for all of its side which make it have a cubic shape. The area of 100 mm cube would be: 6 * side * side= 6 * 100 * 100 = 60,000 mm2

The volume of the cube would be: side^3= 100mm^3=1,000,000 mm3

If broken into 10mm cube, it would form 1000 cube. The total area of the cube would be: 1000 * 6* 10 * 10= 600,000 mm2

NutraSweet (aspartame) is not a carbohydrate but rather a modified dipeptide. What is the biochemical explanation for why this m
True [87]

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.
