Which lists the carbohydrates in order of increasing chemical energy?
a monosaccharides, polysaccharides, disaccharides
b disaccharides, monosaccharides, polysaccharides
c polysaccharides, disaccharides, monosaccharides
d monosaccharides, disaccharides, polysaccharides

Option (d) is the correct answer.

Explanation:

The energy required to be absorbed or released during formation of a chemical bond is known as chemical energy.

Therefore, more is the number of bonds present in a compound more will be its chemical energy.

A monosaccharide is a sugar which upon hydrolysis cannot give simpler sugars.

Whereas a disaccharide on hydrolysis give two molecules of monosaccharides and a polysaccharide gives number of sugar molecules.

Hence, number of bonds increases from monosaccharides to polysaccharides.

Thus, we can conclude that the carbohydrates in order of increasing chemical energy are monosaccharides, disaccharides, polysaccharides.

c) should be the answer.
