Question

1. the properties and functions of molecules are determined by how the subunits in a polymer are joined together. starch (a) potato glycogen (b) liver cellulose (c) agave 1. how many glucose monomers are shown connected together in starch? 2. which carbohydrate is made up of 1 linear chain? starch, glycogen, or cellulose? 3. which carb is made up of 3 linear chains connected together? 4. which carb is made up of 1 polymer with a few branches?

Explanation:

Sub - question 1:

Step 1: Observe the starch structure

From the diagram of starch, we can count the number of glucose monomers (the hexagonal - shaped units) connected in the starch chain shown. By visually inspecting the starch structure, we can see that there are 5 glucose monomers connected together.

Starch is composed of two types of molecules: amylose (a linear chain of glucose units) and amylopectin (a branched chain of glucose units). But when considering the linear chain component, starch has a linear chain of glucose monomers. Glycogen is highly branched, and cellulose has a different type of linkage and structure with linear chains that are hydrogen - bonded to form strong structures, but its main function and structure differ from the linear chain of starch in terms of energy storage. So the carbohydrate with a linear chain of glucose monomers is starch.

Cellulose is made up of long linear chains of glucose monomers. These linear chains are then connected to each other through hydrogen bonds, forming a strong, rigid structure. Starch has a mix of linear (amylose) and branched (amylopectin) chains, and glycogen is highly branched. So the carbohydrate made up of 3 (or multiple) linear chains connected together is cellulose.
