Membrane Receptor Proteins

• Signal molecules bind to receptor proteins and
  causes a change in the cell
• Changes in permeability
• Open ion channel
• Second messengers
• Activates another protein inside the cell
• Enzyme action
• Speeds up a reaction

Test Review

• Passive Transport no energy
• Diffusion
• Definition
• H20, CO2, O2
• Equilibrium
• Ink in a beaker
• Osmosis
• Definition
• Hypotonic
• Hypertonic
• Isotonic

11
Test Review

• Passive Transport (cont.)
• Facilitated diffusion
• Transport proteins
• Ion channels
• Sugar
• Active transport (uses NRG)
• Against concentration gradient
• Uses ATP
• Transport protein
• Na/K Pump

12
Test Review

• Active Transport
• Exocytosis
• Excretion
• Secretion
• Endocytosis
• Problems
• Contractile Vacuole
• Diffusion, facilitated diffusion, active
  transport?
• Why is it dangerous for humans to drink sea water?

13
Cellular Energy

• Adenosine adenine ribose
• ATP - adenosine tri(3)phosphate - used by the
  cell for energy
• Energy currency
• Energy stored in PO43- bonds
• ADP - Adenosine Di(2)phosphate - used to
  regenerate ATP
• Burning vs cellular respiration
• Burning is uncontrolled (fast), cellular
  respiration controlled by enzymes (slow)

ATP/ADP cycle

• Energy used for growth, reproduction, movement
  and active transport
• Drives most of cells activities
