Question 11

Carbohydrates

Answer 11

-Provides energy for the body
- Sugar gives energy

Question 12

Carbohydrates in the body

Answer 12

-Monosaccharides
-Disaccharides
-Polysaccharides

Question 13

Monosaccharides

Answer 13

Simple Sugars:
Glucose
Fructose
Galactose

Question 14

Disacharides

Answer 14

Sucrose
lactose
maltose

Question 15

How do we achieve disaccharides?

Answer 15

Disaccharides must be broken down to monosaccharides before the body can absorbed them.
-Removing water from a bond in this case water from disaccharide for absorption
-Removing water to combine two sugars is what makes a disaccharide.

Question 16

How do we get Maltose?

Answer 16

glc + glc

Question 17

How do we get Sucrose?

Answer 17

glc + fructose

Question 18

How do we get Lactose?

Answer 18

glc + galatose

Question 19

Hydrolysis

Answer 19

Adding water to break down to monosaccharide.

Question 20

Polysaccharides

Answer 20

Glycogen
Starch
Cellulose
Formed by dehydration which will add more sugars together.
