3.2 Cell Organelles LEQ: How does the cytoplasm and cytoskeleton support cell function? Reading 3.2, 12.4 (evolution of mitochondria, chloroplasts only) Test Monday; projects friday Activator: What’s in my head?...about transport across membranes Key terms – cytoskeleton, cytoplasm

3.2 Cell Organelles The cytoplasm is the fluid-filled space between the cell membrane and the nucleus. Metabolic reactions take place here –Metabolic pathways Diffusion of reactants, ions, etc. Positioning of the nucleus, organelles, etc. Cytoskeleton, vesicle traffic

3.2 Cell Organelles Examples of simple metabolic pathways

3.2 Cell Organelles Pathways can be classified as anabolic or catabolic

3.2 Cell Organelles Transport, feedback controls how metabolic pathways operate

3.2 Cell Organelles Eukaryotic cells have an internal structure. The cytoskeleton is a protein network that has many functions: – –supports and shapes cell membrane – –helps position organelles – –vesicle movement – –assists in cell division – –aids in cell movement Bacteria

3.2 Cell Organelles Vesicles can transport chemicals in bulk from the membrane

3.2 Cell Organelles Summary: What are some functions of the cytoplasm? What are the functions of the cytoskeleton?
