Question

name _____________ class__ date ____ macromolecules for questions 6–8, circle the letter of the correct answer. 6 the characteristic that best defines a macromolecule is its a size. c life cycle. b function. d chemical makeup. 7 all of the following macromolecules are polymers except a lipids. c nucleic acids. b proteins. d carbohydrates. 8 all of the following are part of a carbohydrate except a carbon. c hydrogen. b oxygen. d phosphorus.

Explanation:

Question 6

Macromolecules are defined by their large size (macro - large). Function, life cycle, and chemical makeup don't uniquely define them as macromolecules. So the correct answer is A.

Polymers are made of repeating units (monomers). Lipids are not polymers as they don't have a repeating monomeric unit in the same way as proteins (amino acid monomers), nucleic acids (nucleotide monomers), and carbohydrates (monosaccharide monomers). So the correct answer is A.

Carbohydrates have the general formula \(C_n(H_2O)_m\), so they contain carbon, hydrogen, and oxygen. Phosphorus is not a component of carbohydrates (it is part of nucleic acids and some lipids like phospholipids). So the correct answer is D.

Answer:

A. size
