Question
Which of the following pairs constitute a monomer and the corresponding polymer? 1. Glucose:starch 2. Amino acid:polypeptide 3. Fatty acid:triglyceride 4. Glucose:celluloseGroup of answer choices1, 2, 41 and 33 and 42, 3, 41 and 2 PreviousNext
Solution
The correct answer is 1, 2, 4.
Here's why:
-
Glucose:starch - Glucose is the monomer, and starch is the polymer. Starch is made up of glucose monomers.
-
Amino acid:polypeptide - Amino acids are the monomers, and polypeptides are the polymers. Polypeptides are made up of amino acid monomers.
-
Fatty acid:triglyceride - This is not a correct pair. Triglycerides are made up of one glycerol and three fatty acids, so they are not polymers of fatty acids.
-
Glucose:cellulose - Glucose is the monomer, and cellulose is the polymer. Cellulose is
