Fill in the blanks for: Membrane Transport by Mind Map: Fill in the blanks for: Membrane Transport

1. Diffusion

1.1. • No energy • Along concentration gradient

1.1.1. Simple

1.1.1.1. directly through membrane or (1)..........

1.1.1.1.1. affecting factors

1.1.2. Facilitated

1.1.2.1. needs carrier protein

1.1.2.1.1. affecting factors

2. Active Transport

2.1. • Needs energy • Against concentration gradient

2.1.1. Primary Active

2.1.1.1. Diretly uses ATP

2.1.1.1.1. Carrier protein uses ATP to move molecules across cell membrane

2.1.2. Secondary Active

2.1.2.1. Energy for transport comes from stored energy of ionic concentration gradient between intracellular and extracellular environments

2.1.2.1.1. Co-transport

2.1.2.1.2. Counter Transport

3. Specialized Transport Mechanisms

3.1. Endocytosis

3.1.1. Material moving into the cell and uses energy

3.1.1.1. Pinocytosis: to drink; smaller molecules

3.1.1.1.1. • Uptake of soluble molecules • (6).......... engulfment of molecules

3.1.1.2. Phagocytosis: to eat; larger molecules

3.1.1.2.1. • Uptake of particulate material • Only (7).......... particles are engulfed

3.1.1.3. Receptor Mediated

3.1.1.3.1. • Uptake of specific molecules using specific (8)..........

3.2. Exocytosis

3.2.1. Material moving (9).......... and uses energy

3.2.1.1. • Process of secreting protein made by cell • Vesicles from Golgi apparatus move toward cell membrane and fuse with it • As fused membranes “flatted out”, vesicle contents are released into the interstitial space • Vesicle membrane is added to the cell membrane to assist in renewal of phospholipid bilayer
