Explain Facilitated Diffusion
Uses a carrier Protein to diffuse across a membrane
What is Secondary Active Transport?
simultaneously moves 2 substances across the membrane
What is diffusion?
the motion when molecules move from one place to another
What is Active transport?
the movement of materials through a cell membrane using cellular energy
Lysosome
pH of 5.0 Digests foreign substances Autophagy
What is permeable through a membrane?(S.U.N)
(SUN)Small, Uncharged Non-Polar, Molecules
Flicks Law of Diffusion
1.Size, 2.permeability, 3.surface area of membrane, 4.Weight, 5.Distance

Golgi Complex
Modifies proteins and lipids Transports through vesicles
Explain Passive transport.
Non energetic transport across a membrane
What is impermeable through a membrane?
Big, Charged, Polar Ion Molecules
Perioxosome
Contain Enzymes Contain Catalase
Endoplasmic Reticulum (Rough)
Detoxifies
What is the difference between integral and peripheral proteins?
Integral proteins are located between the inner and outer membrane while peripheral proteins are located on either the inner or outer membrane. Not both!
What are the functions of membrane proteins?L-C.R.A.F.T.
Linker, Cell ID Maker, Receptor Proteins, Act as Enzymes, Formation of channels, Transporter Proteins

Ribosomes
Protein Synthesis
Autophagy
Recycles own organelles
Isotonic solution
Same
Explain Simple Diffusion (Osmosis)
Simple diffusion is when no energy or transport proteins are used to diffuse across a membrane.
What factors influence diffusion rates?(S.T.S.D.S.)
Size, Temperature, Surface Area, Distance, Steepness of Gradient.
Proteasomes
Structures that destroy unneeded, damaged, or faulty proteins.
Tonicity
The effect the solution has on the cell
