What are the common categories of lipids?
Fats, oils, and waxes.
Match the following monomer with it's polymer: Fatty acids and glycerol
Phospholipids; Triglyceride
True or False: Nucleic Acids store and transmit hereditary, or genetic, information. (TYPE FOR PRACTICE)
True Nucleic Acids store and transmit hereditary, or genetic, information.
The polymers formed by monosaccharides are known as what?
Complex Carbohydrates., or polysaccharides
Match the following monomer with it's polymer(s): Monosaccharides
Polysaccharide; Glycogen
What do proteins do?
Some proteins control the rate of reactions and regulate cell processes. Some form important cellular structures, while others transport substances to help fight disease.
Match the following monomer with it's polymer: Glucose
Starch
What are carbohydrates?
They are compounds made up of carbon, hydrogen, and oxygen, usually in a ratio of about 1:2:1
Amino Acids are made of what?
They are compounds with an amino group on one side and a carboxyl group on the other side.
When polymers are broken down into monomers, what does your body do with those monomers?
They store them, and use them as energy.
What are phospholipids made of?
Two fatty acids and a phosphate group bound to a glycerol backbone.
How many kinds of nucleic acids; what are they?
Two; RNA and DNA
Nucleotides consist of what three parts?
A 5-carbon sugar, a phosphate group (-PO4), and a nitrogen base.
What is an unsaturated fat?
A fatty acid in which there is at least one carbon-carbon DOUBLE BOND
What is a saturated fat?
A fatty acid that contains the maximum number of hydrogen atoms. It has SINGLE bonds
What is a monomer?
A monomer is a single molecule. Many monomers connect to make polymers
What is a polymer?
A polymer is a collection of monomers. An example of a polymer is DNA.
Match the following monomer(s) to it's macromolecule: Monosaccharide
Carbohydrate
Match the following polymer(s) to it's macromolecule: Cellulose; Polysaccharides
Carbohydrates
What are Carbohydrates/ Why are they needed?
Carbohydrates are used as a main source of energy and is in plant cell walls.
Lipids are made mostly from what?
Carbon and Hydrogen atoms
Match the following monomer with it's polymer: Amino Acid
Enzymes; Protein Collagen
Match the following monomer(s) to it's macromolecule: Fatty acids and glycerol
Lipids
Match the following polymer(s) to it's macromolecule: Triglyceride; Cholesterol
Lipids
What are lipids used for/ Why are they needed?
Lipids can be used to store energy. Some lipids are important parts of biological membranes and waterproof coverings.
How are monomers related to polymers?
Monomers form together to make polymers.
What are simple sugars also known as?
Monosaccharaides
Proteins are macromolecules that contain what?
Nitrogen, Carbon, Hydrogen, and Oxygen.
