| Question | Answer |
|---|---|
| Passive Processes | no energy expenditure required |
| Active processes | cellular energy expenditure required |
| Carrier mediated transport | facilitated diffusion and active transport |
| homeostasis | sodium potassium exchange pump |
| vesicular transport | endocytosis and exocytosis |
| pinocytosis | "cell drinking" |
| Phagocytosis | "cell eating" |
| Cilia | moves fluids across cell membrane |
| flagella | move a cell through surrounding fluid ex sperm |
| apoptosis | death of cells |
| Cells | building blocks of the human body |
| extracellular fluid | interstital fluid |
| Cell Membrane | provides isolation protection sensitivity and support; controls entrance and exits of materials |
| cytosol | distributes materials by diffusion |
| Centrioles | essential for movement of chromosomes during cell division |
| Ribosomes | synthesize protiens |
| Proteasomes | break down and recycle damaged or abnormal intracellular protiens |
| microvilli | increases surface area to facilitate absorption of extracellular materials |
| Endoplasmic Reticulum | Sythesizes secretory products; provides intracelluar storage and transport |
| Rough ER | Packages newly formes protiens |
| Smooth ER | synthesizes lipids and carbs |
| Golgi Apparatus | Stores altars and packages secretory products forms lysosomes |
| Lysosomes | remove damaged organelles or pathogens within cells |
| Peroxisomes | Catabolize fats and other organis compounds; neutralize toxic compounds generated in the process |
| Mitochondria | Produce 95% of ATP required by the cell |
| Nucleus | contols metabolism stores and processes genetic info; controls protien synthesis |
| Nucleolus | synthesizes RNA and assembles ribosomal sub units |
| osmotic pressure | force of water movement into that solution |
| hypotonic | solution with lower concentration of solutes than with in the cell |
| Hypertonic | solution that has a greater concentration of solutes than that with in the cell |
| hemolysis | burst of blood cell |
| crenation | shriveling of blood cell |
| Filtration | pressure forces water across membrane |
| ion pumps | actively transports sodium potassium calcium and magnesium across cell membrane |
| Exchange pump | carrier protien |
