Study Notes
Module 1 Guided Notes
- The video provided goes over all concepts in Module 1.
- Quick Links are available at the bottom of each section. These links are helpful for easy navigation.
- Topics include Exploring Life, Chemistry of Life, Chemistry of Life (Honors), and Earth's Early Atmosphere.
- The first page of the Biology Notebook introduces macromolecules.
- Key organic macromolecules include carbohydrates, lipids, nucleic acids, and proteins.
- These molecules have common functions related to providing energy and the structure of living organisms.
- Page 2 discusses biological macromolecules and defines a monomer.
Biological Macromolecules
- A monomer is a molecule that can react with other molecules to form a larger polymer chain.
- Polymers are made of monomers.
- The four major macromolecules are carbohydrates, lipids, proteins, and nucleic acids.
- Each macromolecule has a different function in living organisms.
Carbohydrates
- Monosaccharides are the smallest type of carbohydrate molecule. Examples include glucose, galactose, and fructose.
- Disaccharides are formed by bonding two monosaccharides together. Examples include sucrose and lactose.
- Polysaccharides are formed by bonding numerous monosaccharides together. Examples include starch, cellulose, and glycogen.
- Carbohydrates provide energy to cells.
Lipids
- Lipids are a diverse group of molecules that are not characterized by repeating structural units (monomers).
- Three main categories of lipids are fats, phospholipids, and steroids.
- Lipids store energy in the body and provide insulation, protection, and cushion to organs
- Triglycerides, composed of one glycerol molecule combined with three fatty acid molecules, are examples of lipids.
Proteins
- Proteins are complex molecules made up of amino acid monomers.
- Proteins can have diverse functions in organisms, including hormones, structural components, enzymes, and antibodies.
- The specific order/arrangement of amino acids in a protein gives proteins their unique properties.
Nucleic Acids
- Nucleic acids are macromolecules that store and transmit genetic information.
- The two major types of nucleic acids are DNA (deoxyribonucleic acid) and RNA (ribonucleic acid).
- Nucleic acids are made up of nucleotide monomers.
- Each nucleotide monomer is composed of three parts: a nitrogenous base, a five-carbon sugar, and a phosphate group.
- The order of the nucleotides in nucleic acids determines the genetic code.
