Question 2 (Multiple Choice, Worth 3 points)

A carbohydrate molecule is:
A. a macromolecule made of amino acids that provides structure for a cell and is not soluble in water.
B. made up of a chain of monosaccharides that transport genetic coding from one end of the cell to another.
C. made up of the monosaccharide glucose and serves as an energy reserve in plants and animals.
D. a chain of amino acids that can be used for protein synthesis, protection, and increasing reaction speeds.



Answer :

Final answer:

Carbohydrate molecules are essential for energy storage and structural support in organisms.


Explanation:

Carbohydrate molecules are made up of the monosaccharide glucose and serve as an energy reserve in plants and animals. They are classified into monosaccharides, disaccharides, and polysaccharides, depending on the number of monomers in the molecule. Carbohydrates play vital roles in providing energy, structural support, and cellular recognition.
