Cell Membrane

Defines Cell

Flexible lipid Bilayer

Presence of Proteins

Hydrophobic Tail, Hydrophilic Head

1 of 7


Lysosomes-  Breakdown Waste, formed in trans-golgi

Nucleus- genetic control, cellular control

Cytoplasm- Fluid, includes organelles and enzymes

Ribosomes- site of protein synthesis, mRNA translation

Proteasomes- protein degradation

Golgi Apparatus- Modifys and transports molecules in ER, two sides= cis and trans

Peroxisomes- Get rid of toxic substances, oxidatives enzymes

Cytoskeleton-  changes shape, network of protein filaments

2 of 7


Microtubules - Structural strength

Actin Filaments - Resppnsible for cell contraction

Intermidiate Filaments- are stable and important in cell junctions

3 of 7

Endoplasmic Reticulum

Important for production of protein and lipid components

Moves proteins and carbohydrates

Rough endoplasmic reticulum - ribosomes (protein synthesis)

Smooth endoplasmic reticulum - newly synthesized proteins are budded off

4 of 7


Energy production and cellular respiration

Outer membrane is similar to plasma membrane contains large proteins.

Inter membrane space contains concentrations of small molecules

Inner membrane expands surface area enhancing ATP production

Matrix- Main area in production of ATP

5 of 7

Cilia, Flagella and Centrioles

All made of microtubules

Cilia and Flagella - made of microtubules, differences in length, good for movement

Centriole - Important in cell division, come in pairs

6 of 7

Types of Junctions Between cells

Tight Junctions - seals neighbouring cells

Adhesion Belt - joins Actin bundles together

Desosome- joins intermediate filaments between cells

Gap Junction - cell to cell communication, passage of small molecules
