Cells
Organelles
-
-
-
Golgi apparatus
Receives proteins from ER, sorts, modifies, repackages for export, plasma membrane growth, creation of lysosomes
-
Mitochondria
ATP synthesis, powerhouse of the cell
Peroxisomes
Enzymes detoxify toxic substances, catalase breaks down hydrogen peroxide
-
-
Microtubules
Supports and gives cell shape, intracellular and cellular movements
Centrioles
Organize a microtubule network to form the spindle and asters during mitosis, form bases of cilia and flagella
Nucleus
Control center of cell, transmits genetic information, provides instructions for protein synthesis
-
Endocytosis
Pinocytosis
"drinking cell", vesicle forms, takes in whatever is outside the cell, non-selective
-
Phagocytosis
"eating cell", phagocytes engulfs an entire cell, cell debris, or pathogens
Membrane Transport
Simple diffusion
Moving down a concentration gradient until equilibrium, small uncharged particles (H2O, CO2), no cell energy required
Facilitated diffusion
Moving down a concentration gradient until equilibrium, larger charged particles (ions), no cell energy required
Active Transport
Moving against a concentration gradient, inform of ATP, variety of substances, cell energy required
Exocytosis
Vesicle forms, travels to surface of cell
