Study Notes
Carbohydrates
- Building blocks of carbohydrates are monosaccharides, such as glucose and fructose.
- Polysaccharides, composed of many monosaccharides linked by glycosidic bonds, serve as energy storage and structural components.
- Glycogen acts as the principal energy storage macromolecule in cells.
Polysaccharides
- Main function of polysaccharides in cells includes energy storage and providing structural integrity, like cellulose in plants.
- Cellulose's primary function is to provide rigidity and strength to plant cell walls.
Taxonomy
- American Black Bear belongs to the Taxonomic rank of species within the order Carnivora.
- Taxonomic ranks follow the order: species, genus, family, order, class, phylum, and domain from most specific to broadest.
- Domain above genus includes Life Domains: Archaea, Bacteria, and Eukarya.
- Taxonomic rank right below Domain is Kingdom.
Binomial Nomenclature
- Scientific name format includes the genus name followed by the species name, both italicized with the genus capitalized.
Phylogenetics
- Field of Biology that studies evolutionary relationships is called systematics, utilizing comparative anatomy, development, and molecular data.
- Each node in a phylogenetic tree represents a common ancestor shared by species.
- A branching event signifies a divergence in the evolutionary path, indicating common ancestry splitting into different lineages.
- Tips in a phylogenetic tree represent existing species or groups.
- Highlighted names in a phylogenetic tree usually represent taxa or ranked groups being studied.
Lipids
- Three types of lipids mentioned include triglycerides, phospholipids, and steroids.
- Lipids are crucial as important energy sources and provide essential fatty acids.
RNA and Protein Synthesis
- RNA functions primarily in protein synthesis and gene expression regulation.
- Ribosomes, located in the cytoplasm and on the endoplasmic reticulum, are responsible for synthesizing proteins.
Cell/Plasma Membrane
- Main function of the Cell/Plasma Membrane in an animal cell is to protect the cell, regulate the passage of substances, and facilitate communication with the external environment.
