unit 3 macro-molecules

Question 1

Macromolecule

Answer 1

A molecule is a group of two or more atoms held together by attractive forces known as chemical bonds; depending on context, the term may or may not include ions that satisfy this criterion.

Question 2

Organic

Answer 2

(of food or farming methods) produced or involving production without the use of chemical fertilizers, pesticides, or other artificial agents

Question 3

Monomer

Answer 3

atoms or small molecules that join together to form more complex structures such as polymers.

Question 4

Polymer

Answer 4

any of a class of natural or synthetic substances composed of very large molecules, called macromolecules, which are multiples of simpler chemical units called monomers.

Question 5

Carbohydrates

Answer 5

A carbohydrate is a biomolecule consisting of carbon, hydrogen and oxygen atoms, usually with a hydrogen–oxygen atom ratio of 2:1 and thus with the empirical formula Cₘₙ, which does not mean the H has

Question 6

Lipids

Answer 6

fatty compounds that perform a variety of functions in your body.

Question 7

Fatty acids

Answer 7

a carboxylic acid consisting of a hydrocarbon chain and a terminal carboxyl group, especially any of those occurring as esters in fats and oils.

Question 8

Protein

Answer 8

made up of building blocks called amino acids.

Question 9

Amino acids

Answer 9

molecules that combine to form proteins.

Question 10

Enzymes

Answer 10

proteins that help speed up chemical reactions in our bodies

Question 11

Catalyst

Answer 11

Catalysis is the increase in rate of a chemical reaction due to an added substance known as a catalyst. Catalysts are not consumed by the reaction and remain unchanged after it

Question 12

Nucleic acids

Answer 12

large biomolecules that play essential roles in all cells and viruses

Question 13

Nucleotide

Answer 13

A molecule that is the basic building block of the nucleic acids DNA and RNA.

Question 14

Hormone

Answer 14

chemical messengers that affect and manage hundreds of bodily processes

Question 15

Steroids

Answer 15

synthetically produced variants of the naturally occurring male hormone testosterone

Question 16

Dehydration synthesis

Answer 16

n chemistry, a dehydration reaction is a chemical reaction that involves the loss of water from the reacting molecule or ion. Dehydration reactions are common processes, the reverse of a hydration reaction.
