Unit 1: Cells, Diffusion & Respiration

2. (1) Cells
Cell = Basic unit of life.
Types:
Prokaryotic
Eukaryotic

3. (2) Organelles Organelle = Specialized membrane structure w/in a cell.
Types:
Nucleus
Endoplasmic Reticulum
Ribosomes
Golgi Apparatus / Body
Mitochondria
Lysosomes

6. (3) Cell Membrane Outermost covering of cells. Structure: Function:
Cell Wall = Exception.
Structure:
Phospholipid Bilayer
Embedded Protein Channels
Function:
Traffic Control

8. (4) Diffusion High  Low…. Until Equilibrium Concentration Gradient
No Energy

10. (5) Osmosis Water High  Low… Until Equilibrium Concentration Gradient
No Energy
Semipermeable Membrane

12. (6) Hypertonic & Hypotonic
Water Solutions
Hyper = [High Solute]
Hypo = [Low Solute]

14. (7) Active Transport Low  High…. Against Equilibrium
Against Concentration Gradient
Energy
Protein Channels

17. (8) Cellular Respiration
Mitochondria
C6H12O6 + 6O2  6CO2 + 6H2O + ATP
Energy Transfer: Glucose  ATP
Carbohydrate Metabolism

20. (9) Homeostasis Stability Conditions: pH  Acids & Bases Temperature
Water
[Ion]  Electrolytes
