5. Carrier proteins – Carrier proteins – proteins that assist facilitated diffusion proteins that assist facilitated diffusion

6. Ion channels – Ion channels – proteins transport ions from high concentration to lower concentration proteins transport ions from high concentration to lower concentration Ions like Na+, Ca+, etc are not soluble in lipids, so they must travel through proteins channels Ions like Na+, Ca+, etc are not soluble in lipids, so they must travel through proteins channels Ion channels are ion specific Ion channels are ion specific Some channels are always open, some have gate Some channels are always open, some have gate Gates open from stimuli: stretching of cell membrane electrical or chemical signals Gates open from stimuli: stretching of cell membrane electrical or chemical signals

8. Active Transport – Active Transport – transport of materials against a concentration gradient – requires energy transport of materials against a concentration gradient – requires energy ATP (adenosine tri-phosphate) – ATP (adenosine tri-phosphate) – the ENERGY molecule for the cell the ENERGY molecule for the cell Breaks down from ATP  ADP (Adenosine di-phosphate) Breaks down from ATP  ADP (Adenosine di-phosphate) Hydrolysis of the phosphate releases energy Hydrolysis of the phosphate releases energy Active Transport
