Question

Why do disaccharides produce more CO2 than monosaccharides?

a. Dissaccharides break down molecules at more than twice the rate that monosaccharides break down molecules.
b. They are made from two monosaccharides stuck together so they can be broken down into twice as much as ethanol, carbon dioxide, and energy.
c. The bond that links the subunits of the disaccharides together is made of carbon dioxide, wo when it is broken extra carbon dioxide is produced.
d. Disaccharides spontaneously break down and the cell needs to actively break down monosaccharides so their carbon dioxide production is slower.

Answer 1

Answer: b. They are made from two monosaccharides stuck together so that they can be broken down into twice as much as ethanol, carbon dioxide and energy.

Step-by-step explanation:

Disaccharides are the molecules of sugars. These are formed by two monosaccharide units. These can be broken down by the process of combustion as a result of which more carbon dioxide will generate as compared to break down of monosaccharides.

Thus break down of disaccharide results in twice amount of products as compared to monosaccharides.
