3.2 Carbs, Lipids, Proteins

Question 0

Three examples of disaccharides.

Answer 0

Maltose
Lactose
Sucrose

Question 1

List three examples of monosaccharides.

Answer 1

Glucose galactose fructose

Question 2

List three examples of polysaccharides.

Answer 2

Starch,
glycogen
cellulose

Question 3

State one function of glucose, lactose, and glycogen in animals.

Answer 3

Glucose: chemical fuel for cell respiration
Lactose: makes up some of the solutes and milk, energy for suckling infants
glycogen: glucose in liver and muscles, short term energy source

Question 4

State one function of fructose sucrose and cellulose in plants.

Answer 4

Fructose: found in many foods make them sweet.

Sucrose:transportable energy form.

Cellulose: primary component of four cell walls/structure.

Question 5

Define hydrolysis and define condensation

*outlining relationship between monosaccharides, disaccharides and polysaccharides; between fatty acids, glycerol, triglyceride; amino acids and polypeptides.

Answer 5

Hydrolysis: reducing large particles to small particles by adding/splitting water

Condensation: reverse, condensing small particles to make a large particles, water is a product

Question 6

State three functions of lipids

Answer 6

1. energy source in the form of fat
2. heat insulation three provide
3. protection against physical injury to organs

Question 7

Compare the use of carbohydrates and lipids and energy storage.

Answer 7

carbs; short-term storage, water-soluble, finally and rapidly digested, contain less energy per gram, stored as glycogen in animals cellulose in plants, affect on osmotic pressure.

Lipid; long-term storage, non-water-soluble, last medley and rapidly digested, contain more energy program approximately two times more, stored as fat in animals /oil in plants, less of that osmotic pressure.
