Answers (100% Pass)
What is a macromolecule? - ✔️✔️molecules made from smaller joining subunits
What are the building blocks of macromolecules? - ✔️✔️monomers
How are macromolecules synthesized (made)? - ✔️✔️dehydration synthesis
Dehydration Synthesis - ✔️✔️A chemical reaction in which two molecules covalently bond
to each other with the removal of a water molecule.
How are macromolecules/polymers broken down? - ✔️✔️Hydrolysis
Hydrolysis - ✔️✔️Breaking down complex molecules by the chemical addition of water
What is a carbohydrate? - ✔️✔️compound made up of carbon, hydrogen, and oxygen
atoms; major source of energy for the human body
What are the major components of a carbohydrate's backbone? - ✔️✔️Carbon,
Hydrogen, Oxygen
Monosaccharide - ✔️✔️A single sugar molecule
Example of monosaccharides: - ✔️✔️glucose or fructose, the simplest type of sugar.
Disaccharide - ✔️✔️A double sugar molecule made of two monosaccharides bonded
together through dehydration synthesis.
Polysaccharide - ✔️✔️Carbohydrates that are made up of more than two
monosaccharides

How are carbohydrates classified? - ✔️✔️by the number of sugar molecules they contain
Glycosidic Linkage - ✔️✔️A covalent bond formed between two monosaccharides by a
dehydration reaction.
What is the difference between starch and cellulose? - ✔️✔️Starch uses 1,4 and 1,6
alpha linkages and has a branched structure, whereas cellulose uses 1,4 beta linkages
and has a rigid, elongated structure.
What are the main functions of carbohydrates? - ✔️✔️Energy Storage and Structure
Lipid - ✔️✔️macromolecule made mostly from carbon and hydrogen atoms; includes fats
and oils (triglycerides), waxes, phospholipids, and steroids
Why aren't lipids true polymers? - ✔️✔️lipids are not composed of repeating units of the
same molecules or atoms
What is the structure of fats? - ✔️✔️glycerol (3C alcohol) + fatty acid
What is the function of fats? - ✔️✔️energy storage
How is a triglyceride made? - ✔️✔️By combining one glycerol molecule with three fatty
acids through dehydration synthesis
Saturated Fats - ✔️✔️solid at room temp, defined by having all single bonds between the
carbons in their hydrocarbon chain.
unsaturated fats - ✔️✔️liquid at room temp, has a double bond in their hydrocarbon chain
monounsaturated fat - ✔️✔️has one double bond
polyunsaturated fat - ✔️✔️has more than one double bond
trans fat - ✔️✔️An unsaturated fat, formed artificially during hydrogenation of oils,
containing one or more trans double bonds. The hydrogens around the double bond in
the hydrocarbon chain are on opposite sides.
