• FUNCTION Construction of Molecules For Use
  In/Out of the Cell
• POSSIBLE DEFECT Deformation or Death

CYTOMEMBRANE SYSTEM

• Contributing Organelles
• Endoplasmic Reticulum (ER)
• Ribosomes
• Golgi Bodies
• Vesicles
• Lysosomes/Peroxisomes
• Cell Membrane

? 2005 GHS High School
5
Endoplasmic Reticulum (ER)

• FUNCTION
• Rough ER makes proteins
• Smooth ER makes lipids
• ANALOGY
• Assembly Line of Factory
• POSSIBLE DEFECTS
• Incorrect structure--deformed or death

6
Ribosomes

• FUNCTION
• Makes proteins by attaching amino acids together
• Either free-floating or attached to ER
• ANALOGY
• Assembly Workers
• POSSIBLE DEFECT
• Incorrect protein structures

7
Golgi Bodies

• FUNCTION
• Put the final touches on lipids and proteins
  (adding carbohydrates) and packages molecules
  into vesicles
• ANALOGY
• Boxing/Packaging
• POSSIBLE DEFECT
• Incorrect Fats/Proteins to disrupt function

? 1999-2002 J.Vilenski
8
Vesicles

• FUNCTION
• Move materials either into or outside the cell
  (EXOCYTOSIS/ ENDOCYTOSIS)
• ANALOGY
• Truck Drivers
• POSSIBLE DEFECT
• Materials build up inside cell causing damage

? 1997 University of Nebraska

Vesicles

• FUNCTION
• Move materials either into or outside the cell
  (EXOCYTOSIS/ ENDOCYTOSIS)
• ANALOGY
• Truck Drivers
• POSSIBLE DEFECT
• Materials build up inside cell causing damage

10
Lysosomes/Peroxisomes

• FUNCTION
• Special digestive enzymes break down lipids,
  proteins, and any toxin that enters cell
• ANALOGY
• Cleaning Crews
• POSSIBLE DEFECT
• Toxic molecules can damage cells, e.x. ALD

? 1997 University of Nebraska
11
MITOCHONDRIA

• ANALOGY
• Power Supply for Cell (Battery)
• FUNCTION
• Breaks down glucose (sugar) to make energy (ATP)
• POSSIBLE DEFECT
• Not enough energy organs fail or fatigued

? 2005 GHS High School
12
NUCLEUS

• ANALOGY
• Government Rules and Laws
• FUNCTION
• Storage of the important code of cell (DNA) and
  gives directions to cell processes
• POSSIBLE DEFECTS
• Damage to DNA causing genetic disorders and/or
  death

? 2005 University of Arkansas

NUCLEUS

• ANALOGY
• Government Rules and Laws
• FUNCTION
• Storage of the important code of cell (DNA) and
  gives directions to cell processes
• POSSIBLE DEFECTS
• Damage to DNA causing genetic disorders and/or
  death

14
CYTOSKELETON

• ANALOGY
• Infrastructure buildings, communication lines,
  and movement

15
CYTOSKELETON

• FUNCTION
• Gives the cells shape, structure and ability to
  move
• Intermediate filaments maintain shape of cell
• Microtubules Help with cell shape and aids in
  DNA division
• Flagellum and cilia aid in movement of either
  cell or particles

? 2005 Beyond Books, Apex Learning Inc.
? 1998 Access Research Network Molecular Machines
Museum
16
CYTOSKELETON

• POSSIBLE DEFECTS
• Incorrect cell shape (think if your nerve cells
  were wrong?!)
• Cells not able to move (Think sperm cells)
• Cells not able to communicate with each other
