Carbohydrates represent important macromolecules in the biochemical pathways of many organisms.
Which of the following is/are monosaccharide(s)?
I. Glucose
II. Fructose
III. Maltose
Glucose and fructose are monomeric saccharides, or monosaccharides. The carbon to hydrogen to oxygen 
ratio exists in a 1:2:1 pattern indicative of a monomeric saccharide. The molecular formula of glucose and fructose is

Disaccharides, such as maltose, are produced when two monosaccharides undergo a dehydration synthesis reaction.
Which of the following formulas represents a disaccharide?
Disaccharides, such as maltose, are produced when two monosaccharides undergo a dehydration synthesis reaction.
Which of the following formulas represents a disaccharide?
The disaccharide maltose is formed by the dehydration synthesis reaction of two glucose monomers. When simply adding the two glucose monomers together, it may be thought that the summation of the two 
will be the chemical formula of maltose. However, this does not account for the dehydration synthesis reaction in which one oxygen atom and two hydrogen atoms disappear. After accounting for these molecules the chemical formula for maltose will be represented by 
.

Animals and plants store glucose in saccharide polymers.
Which of the following is the polymer form of storage in plants and animals, respectively?
Animals and plants store glucose in saccharide polymers.
Which of the following is the polymer form of storage in plants and animals, respectively?
The sugar polymer form in which plants store energy is starch, whereas with animals, it is glycogen. While the other answers may in fact be sugar molecules involved in energy metabolism, they do not represent the primary sugar polymer storage molecule. Therefore the correct form of storage for plants is starch. And the correct form of storage for animals is glycogen.

In which of the following molecular forms do animals store energy?
In which of the following molecular forms do animals store energy?
Both lipids (fat) and glycogen (made up of glucose molecules) store energy in animals. Lipids are used for long-term energy storage while glycogen, found in the liver and muscles, is used for short-term energy storage. Peptidoglycan is the molecule that makes up the bacterial cell walls.
