Study Notes
Cell Structures and Functions
- Nucleus: Contains the cell's genetic material (DNA) and controls cell activities by regulating gene expression
- Peroxisome: Contains enzymes that break down fatty acids, amino acids, and certain chemicals, producing hydrogen peroxide as a byproduct which gets converted to water.
- Rough ER: Studded with ribosomes, involved in protein synthesis and processing
- Ribosome: Small structures that produce proteins; found floating freely in the cytoplasm or attached to the endoplasmic reticulum.
- Smooth ER: Lacks ribosomes, involved in lipid synthesis and detoxification processes
- Vesicle: Small membrane-bound sacs that transport and store substances inside the cell; also aid in transporting materials to and from the cell surface
- Cell: The basic unit of life
- Cell membrane: A semi-permeable membrane that surrounds the cell. Provides protection, structure, and controls the movement of substances in and out of the cell.
- Mitochondrion: Known as the powerhouse of the cell, generates most of the cell's ATP (energy) through cellular respiration
- Nucleolus: Involved in producing and assembling ribosome components
- Centriole: Involved in cell division; helps in the formation of spindle fibers that separate chromosomes during mitosis
- Cytosol: The jelly-like fluid inside the cell that holds the organelles and is the site of many metabolic reactions
- Cytoskeleton: A network of fibers that provides structural support for the cell, aids in cell movement, helps transport materials inside the cell.
- Nuclear DNA: Contains the genetic blueprint for the organism, encoding instructions for protein synthesis and cell function.
- Golgi complex: Modifies, sorts, and packages proteins and lipids for storage or transport out of the cell
- Lysosome: Contains digestive enzymes that break down waste materials, cellular debris, and foreign invaders like bacteria.
