Carbohydrates - 3

Question 1

shape

Answer 1

ring structure
1:2:1 ratio in all monomers

Question 2

monomer

Answer 2

monosaccharides

Question 3

polymer

Answer 3

disaccharides or polysaccharides

Question 4

simple sugars

Answer 4

quickly broken down by the body because they are smaller molecules

Question 5

complex carbohydrates

Answer 5

larger molecules like starch and fiber, which take longer to digest and give you that a sense of feeling full for more time

Question 6

polysaccharide

Answer 6

• a long chain of monosacharides
• complex sugars made up of 100’s of monomers
• function in the cell as storage molecules or form structural compounds like cell walls and provide long term sources of energy

Question 7

Important Polysaccharides

Answer 7

• starch
• glycogen
• cellulose
• chitin

Question 8

starch

Answer 8

energy storage molecule in plants

ex. potatoes and carrots

Question 9

glycogen

Answer 9

energy storage molecule in animals

found in liver & muscles

Question 10

cellulose

Answer 10

structure in plants that forms the cell walls

ex. celery

Question 11

chitin

Answer 11

structure in arrthropods and fungi that forms the exoskeleton

Question 12

In plant molecules,

Answer 12

• the glucose that makes up the molecule are slightly different and affect their 3D shape
• starch contains alpha glucose, while cellulose is made of beta glucose
• this makes cellulose indigestible in humans

starch = easy to digest
cellulose = animals cannot digest

Question 13

sugars = quick energy

Answer 13

starches = longer lasting energy
