Metabolism: how cells acquire, transform, store, and use energy

Polymerization: Large compounds are constructed by joining together smaller compounds.

Monomers (smaller cpds) are joined together to form polymers

Composed of carbon, hydrogen, oxygen - C, H, O

A. Function Main source of energy: stored

in the bonds released when bonds are broken

Absorbed in the digestive tract as glucose enters

Breaks down complex carbohydrates

If not used stored or excess can be converted to fat

About 50% of the body’s calorie intake should be from carbohydrates

Sugars and starches Plant food such as fruits, vegetables,

grains Refined: much of the nutritional value

and nutrients have been stripped away white flour, white rice, cakes biscuits and

snack foods Your body cannot break down cellulose

– but referred to as fiber (is important!)

a) Monosaccharides – simple (single) sugars

Monomers: glucose, galactose, fructose

b) Disaccharides – double sugars Polymers: sucrose (glucose + fructose) lactose (galactose + glucose)

c) PolysaccharidesPolymers: starch and cellulose (in plants),

& glycogen (in animals)

Used for: storing energy

- “loss of water while putting together”

This is how complex carbohydrates are made (these can be stored)

The chemical bond is formed between the “- OH” groups in each molecule

Draw (on overhead)

- “water splitting” A water molecule is added to split

apart complex carbohydrates

Important to the human body because the digestive system must break down the complex carbohydrates

Once complex carbohydrates are broken down, they can be used in cellular respiration

Fats, oils or waxes Composed of carbon, oxygen

& hydrogen (C, O, H)

1)store energy (hibernation) - insulation2)form biological membranes phospholipid bilayer of cell membranes

Why? helps limit what can enter & exit the cellhydrophobic & hydrophilic parts

3) used as chemical messengers (hormones)

1) Broken down into fatty acids

2) Stored in body tissues Used to store or release energy Fatty acids + glycerol

[dehydration synthesis]

Unsaturated lipids: there is 1 or more carbon to carbon double bonds Does NOT contain the max. number

of hydrogen atoms possible Healthier – Found in olive oil,

fish oils, avocados,

Saturated lipids: carbon to carbon single bonds Contains the maximum (saturated) number of hydrogen atoms possible

Less healthy – Found in animal products

In meat, eggs, & cheese: harder to digest

Composed of nitrogen, carbon, hydrogen, oxygen (N, C, H, O)

Monomers: amino acids (there are 20 common amino acids)

Peptide bond: joins 2 amino acids[A dehydration synthesis]

1. Growth & repair of tissue

2. Transport (hemoglobin transports oxygen)

3. Pump small molecules in and out of cells

1. Digestive enzymes break down into amino acids

2. When needed, proteins can enter the Citric Acid Cycle (cellular respiration) to help us get energy

Eggs, milk, meat, fish, poultry
