Question 11

Dehydration Reaction

Answer 11

 Form a covalent bond between two monomer
 Called “Condensation
 For every subunit added to a macromolecule
• One water molecule is removed

Question 12

Catalysis (Dehydration Reaction)

Answer 12

• Positioning and stressing

* Carried out within cells by enzymes

Question 13

o Hydrolysis Reactions

Answer 13

 Reversed dehydration reaction
• Molecule of water is added instead of removed
 Hydrogen atom is attached to one subunit
 Hydroxyl group is attached to another
• Both breaking the covalent bond

• 6 carbon sugars

Answer 17

o Straight-chain form
o When dissolved in water
 Form rings

Question 18

 Disaccharides

Answer 18

o Transport molecules
o Provide nutrition in animals
o Two monosaccharides linked together
o Reservoirs of glucose

Question 19

• Sucrose

Answer 19

o Glucose + Fructose

Question 20

• Lactose

Answer 20

o Glucose + Galactose

Question 21

 Polysaccharides

Answer 21

• Long polymers
o Monosaccharides
• Joined together by dehydration reactions
