Biological Molecules: Structure and Properties of Glycogen

Question 1

What is the glucose storage molecule in animals called?

Answer 1

= Gylocgen.
= major stores are found in the liver and muscle cells.

Question 2

What is the structure of glycogen molecules?

Answer 2

= polysaccharide of alpha glucose molecules
= joined by a 1-4 glycocidic bond
= branches joined by 1-6 glycocidic bond.

Question 3

What is the difference between amylopectin and glycogen?

Answer 3

= more branched
= compact molecule

Question 3

What is the difference between amylopectin and glycogen?

Answer 3

= more branched
= compact molecule

Question 4

The enyzmes that break down glycogen act at the ends of the molecules, how does glycogen’s structure impact this?

Answer 4

= enzymes act the end of molecules
= heavily branched
= rapidly breaks down into glucose.

Question 5

Unlike glucose what is glycogen?

Answer 5

= Insoluable
= Too big to diffuuse

Question 6

Why is a rapid rate in enyzmes important?

Answer 6

= Animals often have a high rate of respiration
= energy needs of animals can change rapidly.

Question 7

What is another advantage of glycogen?

Answer 7

= polymer- easy to hydrlolyse into glucols-e this glucose is good for respiratio
