1.4 Starch And Glycogen

Question 1

What two monomers make up starch?

Answer 1

Maltose and Glucose

Question 2

What is the point in a polysaccharide having many branches?

Answer 2

It is easier for enzymes to break them down resulting in energy being released faster

Question 3

Which type of bond results in polysaccharides branching?

Answer 3

1-6 glycosidic bond

Question 4

What two polysaccharides is starch made out of?

Answer 4

Amylose and Amylopectin

Question 5

Which of starch and glycogen have more branches and why?

Answer 5

Glycogen has more branches because animals need more energy than plants

Question 6

Describe the structure of Amylose and its properties

Answer 6

A coiled structure
Held together by hydrogen bonds
Insoluble

Question 7

Describe the structure and properties of Amylopectin

Answer 7

In branches
Held together by hydrogen bonds
Insoluble

Question 8

Why is it useful for a cell if Amylopectin and Amylose are insoluble

Answer 8

So glucose won’t change the osmotic level as glucose would break down

Question 9

Describe the structure and properties of glycogen

Answer 9

In branches
Made of glucose
Stored in the liver and muscles
Insoluble

Question 10

Why do polymers form the structure they do?

Answer 10

So they can be as compact as possible to store as much energy as possible
