Carbohydrates, lipids, nucleic acids, proteins
Term
2) All biomolecules have which element in common?
Definition
they all contain carbon
Term
3) Carbohydrates
Carbohydrates.

what elements make up carbs?
Definition
carbon, hydrogen, oxygen
Term
What are the monomers (building blocks) of carbohydrates?
Definition
Monosaccharide, Diassachirde, and Polysaccharide
Term
Explain the difference between a monosaccharide (sugar), diassachirde, and a polysaccharide (starch).
Definition
Polysaccharides are mainly found in plants. Monosaccharides are simple sugars made up three simple parts while Diassachirde are more precise
Term
What are the uses for carbohydrates?
Definition
They are the main source of energy of living things
Term
Give examples of carbohydrates.
Definition
Starch, Glucose, and Lactose
Term
What two parts make up a lipid?
Definition
Carbon and Hydrogen
Term
What are the uses for lipids?
Definition
For storing energy, and make up waterproof coverings cell membranes and steroids
Term
Name some examples of lipids.
Definition
Saturated and unsaturated fats
Term
Explain the difference between saturated and unsaturated fats
Definition
Saturated are shortening and can only have single bonds. Unsaturated are liquids and can have one or more double bonds
Term
Nucleic acid is built from monomers (subunits) called?
Definition
Nucleotide, Amino acids structure, and Amino acids in DNA
Term
What are the three parts of a nucleotide?
Definition
Sugar, Phosphate, and Nitrogenous
Term
What are the uses of nucleic acids? List two types
Definition
To store and transmit hereditary information. The two groups are RNA and DNA
Term
Proteins are built from monomers (subunits) called?
Definition
Amino acids and carboxyl
Term
List some uses of proteins.
Definition
Control reaction rates, regulate cell processes, transporting substances, and fighting diseases
Term
