Study Notes
Cell Cytoplasm
- Cells are the basic structural and functional units of all multicellular organisms
- Cells have two main compartments: cytoplasm and nucleus
- Organelles are complex compartments with specific metabolic activity
- Organelles are categorized into membranous and non-membranous structures
Membranous Organelles
- Plasma Membrane: A lipid bilayer structure, containing proteins, cholesterol, and phospholipids. It regulates the passage of substances into and out of the cell, and facilitates various cellular processes.
-
Endoplasmic Reticulum (ER): A network of tubules and sacs.
- Rough ER: Studded with ribosomes, responsible for protein synthesis and modification.
- Smooth ER: Lacks ribosomes, involved in lipid synthesis, steroid hormone production, and detoxification.
- Golgi Apparatus: A stack of flattened sacs (cisternae) processing, packaging, and sorting proteins and lipids for secretion or intracellular transport.
- Endosomes: Membrane-bound vesicles involved in endocytosis, sorting incoming materials, and directing them to other cellular compartments for processing or recycling.
- Lysosomes: Membrane-bound vesicles containing hydrolytic enzymes for intracellular digestion.
- Mitochondria: Double-membrane organelles responsible for generating ATP through cellular respiration.
- Peroxisomes: Involved in various metabolic reactions, including fatty acid oxidation and detoxification.
Non-membranous Organelles
- Microtubules: Hollow, cylindrical structures made of tubulin dimers for cell shape maintenance, intracellular transport, and cellular movements like chromosome separation during cell division.
- Actin Filaments (Microfilaments): Threaded protein fibers for cell shape, movement, and contraction, particularly important for muscle cells, cell motility and cell division.
- Intermediate Filaments: More stable protein fibers of varied types to provide structural support and mechanical resistance to cells.
Inclusions
- Lipofuscin: A byproduct of cellular aging and degradation processes, often appearing as pigmented granules.
- Hemosiderin: Iron-containing granules resulting from the breakdown of hemoglobin, often visible in specific cells like macrophages.
- Glycogen: Stored glucose for energy, often accumulating in liver and muscle cells.
- Lipid Droplets: Stored lipids/fatty acids, found in a variety of cells.
- Crystalline inclusions: Crystals formed of various substances, depending on the cell type.
