CH 6: Carbon Chemistry (PS)

Repeating chains of small molecules form large molecules (macromolecules) or __________________, in the process of polymerization.

Carbohydrates and lipids are similar in that they are made up of (select all that apply), but in different ratios.

• carbon

• hydrogen

• oxygen

• nitrogen

Why do atoms bond together?

• for stability: to complete their outer shell with electrons

• to help out the other elements

• atoms are not meant to be alone

• all organic compounds need to be bonded

Macromolecule concerned with insulation, long-term energy storage, and chemical messengers (steroids)

• carbohydrates

• lipids

• proteins

• nucleic acids

Macromolecule made up of CHONP, contains the genetic information; monomers are made of a sugar, nitrogen base, and phosphate group.

• carbohydrates

• lipids

• proteins

• nucleic acids

Carbon is considered the backbone of living things because

• carbon contains 4 valence electrons and can bond with 4 more atoms

• carbon can bond with itself and form long chains or polymers

• carbon bonds are strong enough to remain intact in water

• carbon bonds are generally stable

When a molecule is organic, it means that:

• it is found in living things

• the compounds contain covalently bonded carbon and hydrogen atoms

• grown without pesticides

• grown in the backyard

In science, what does it mean if something is "organic"?

• It is naturally made food items.
• It is made up of carbon and was once living
• It has no pesticides
• It is healthier for you.
