The 4 main elements that make up 95% of an organism are:

• Carbon, Hydrogen, Oxygen, Nitrogen

• Carbon, Calcium, Phosphorus, Potassium

• Oxygen, Sodium, Chlorine, Magnesium

• Hydrogen, Sulfur, Iron, Zinc

A macromolecule is made up of:

• smaller molecules called monomers

• atoms only

• ions only

• single large atoms

The four classes of macromolecules are:

• Carbohydrates, lipids, proteins, and nucleic acids

• Carbohydrates, vitamins, minerals, and water

• Lipids, enzymes, hormones, and DNA

• Proteins, starch, cellulose, and glucose

Use the diagram of glucose below to tell how many carbons, hydrogens, and oxygens are in a single molecule. HINT: COUNT THE # of C's, H's, and O's in the molecule below.

• C 6 H 12 O 6

• C 5 H 10 O 5

• C 4 H 8 O 4

• C 7 H 14 O 7

Proteins also act as __________________________ in cells to control reactions.

• enzymes

• hormones

• lipids

• carbohydrates

Lipids are nonpolar. This means that:

• they do not mix well with water.

• they dissolve easily in water.

• they are attracted to water molecules.

• they are made of charged particles.
