Unit 3 List 1 Macromolecules

Question 1

Macromolecule

Answer 1

a very large molecule made up of many smaller, repeating building blocks (monomers), like a long chain of LEGO bricks.

Question 2

Organic

Answer 2

carbon-containing compounds that are the basis for all living organisms.

Question 3

Monomer

Answer 3

Monomers are small molecules that can be joined to form more complex molecules

Question 4

Polymer

Answer 4

a long chain made of many small, repeating building blocks called monomers, like a necklace made of beads.

Question 5

Carbohydrates

Answer 5

a type of food that your body uses for energy, like the fuel for your body’s engine, and they’re made up of sugar molecules.

Question 6

Lipids

Answer 6

a group of substances, like fats and oils, that don’t mix with water and are important for energy storage, cell structure, and hormone production.

Question 7

Fatty acids

Answer 7

like the building blocks of fats and oils, made of long chains of carbon atoms, and are important for energy and building cells.

Question 8

Protein

Answer 8

proteins are like the building blocks of your body, made of smaller units called amino acids, and they help your body grow, repair itself, and do many other important things.

Question 9

Amino acids

Answer 9

the building blocks that make up proteins, which are important for everything your body does, from growing to repairing itself.

Question 10

Enzymes

Answer 10

special proteins that act like tiny helpers inside your body, speeding up chemical reactions that are vital for life, like digestion and building new cells.

Question 11

Catalyst

Answer 11

a substance that speeds up a chemical reaction without being used up itself.

Question 12

Nucleic acids

Answer 12

molecules that hold the instructions for how our bodies work.

Question 13

Nucleotide

Answer 13

a compound consisting of a nucleoside linked to a phosphate group. Nucleotides form the basic structural unit of nucleic acids such as DNA.

Question 14

Hormone

Answer 14

Hormones are chemical substances that act like messenger molecules in the body.

Question 15

Steroids

Answer 15

Steroids are a type of organic compound that includes hormones and vitamins, characterized by a specific molecular structure of four carbon rings.

Question 16

Dehydration synthesis

Answer 16

occurs when two molecules or compounds are joined to form a larger molecule following the removal of water.

Question 17

Hydrolysis
