Study Notes
Organelle Overview
- Nucleus: Variable location within the cell; stores genetic material (DNA) and nucleoli; key for RNA synthesis and ribosomal subunit assembly.
- Ribosomes: Found in the cytoplasm; crucial site for protein synthesis from amino acids.
- Rough endoplasmic reticulum (rough ER): Located in the cytoplasm with ribosomes attached; primarily responsible for synthesizing proteins.
Membrane-bound Organelles
- Smooth endoplasmic reticulum (smooth ER): Present in the cytoplasm; involved in lipid synthesis and detoxification processes.
- Golgi apparatus: Situated in the cytoplasm; modifies proteins received from the rough ER and packages them into secretory vesicles.
- Secretory vesicle: In cytoplasm; transports materials produced by the cell, created from the Golgi apparatus, and released via exocytosis.
- Lysosome: Located in the cytoplasm; contains digestive enzymes that break down materials entering the cell; also formed by the Golgi apparatus.
- Peroxisome: Found in the cytoplasm; responsible for breaking down fatty acids, amino acids, and hydrogen peroxide.
Energy Production and Structure
- Mitochondrion: Located in the cytoplasm; major site of aerobic respiration and ATP synthesis, essential for cellular energy.
- Microtubule: Supports the cytoplasm; aids in cell division and forms structural components of cilia and flagella.
- Centrioles: Found in the cytoplasm; play a vital role in chromosome movement during cell division.
Cellular Projections
- Cilia: Located on cell surface, typically numerous; help in moving substances over cell surfaces.
- Flagella: Present on sperm cells, usually one per cell; facilitate propulsion of sperm cells.
- Microvilli: Extensions of cell surfaces, abundant on certain cells; increase surface area for absorption and secretion.
