IPHY 3410 1st Edition Lecture 1 Outline of Current Lecture1) Describe the functions and characteristics of plasma membrane, ER, Golgi, lysosomes, and mitochondria.2) Interpret the cell type based on the abundance of certain organelles3) Describe the function of three specialized contacts/junctions4) Predict the location of specialized junctions based on their functions5) Describe the function of three cytoskeletal elements6) Compare and contrast the three cytoskeletal elementsCurrent LectureCells – the fundamental living unitFunctions- Import nutrients- Make additional molecules from nutrients- Dispose of waste- Maintain shape/structure- Replicate itselfParts of a CellCytoplasm – intracellular fluid; contains fluid cytosol and organellesPlasma Membrane – phospholipid bilayer which separates extracellular and intracellular layers- Protein molecules identify cells and transport them in and outo Attached to membraneEndoplasmic Reticulum – stores calcium for communication and muscle activation- Smooth ER – lipid assembly and metabolism- Rough ER – ribosomes assemble proteinsGolgi Apparatus – sorts, processes, and packages proteins and membranes made by Rough ER- Makes lysosomes which clean up cell- Produces vesicles that contain proteinsLysosomes – contain digestive enzymes produced by Rough ERMitochondria – performs glycolysis and oxidation which both produce ATP- Contain its own DNA and RNA - Contains its own DNA and RNA- Metabolism comes from maternal linkage (your mother)- Has a large surface area due to folds- Muscle cells have a lot; red blood cells don’t These notes represent a detailed interpretation of the professor’s lecture. GradeBuddy is best used as a supplement to your own notes, not as a substitute.Cytoskeleton- Microfilament – actin and myosin filamentso Just below cell membraneo Generate contractile force for movement- Microtubule – shaped like a latticeo Hollow tubes of tubulin proteino Attachment site for organelles- Intermediate Filamento Protein fibers are wound like ropeo Resist pulling forces and resist tensionNucleus- Contains DNA- Typically one per cell, but can have more than
