Q2 Mod6&10 Transport Mechanisms Flashcards
High to Low
Passive
2 Types of Transport Mechanism
Passive & Active
Low to High
Active
A type of transport mechanism that does NOT require ATP
Passive
Two types of diffusion
Simple & Facilitated
A type of diffusion that happens when there is a difference in concentration with nonpolar solutes (CO2, O)
Simple Diffusion
A type of diffusion that happens when there is a difference in concentration with polar solutes between two areas
Facilitated Diffusion
A type of diffusion that is helped by the transmembrane
Facilitated Diffusion
Two types of Facilitated Diffusion
- Channel Mediated Diffusion
- Carrier Mediated Diffusion
Two types of Channel Mediated Diffusion
- Leak Channel
- Gated Channel
Type of Channel Mediated Diffusion that is ALWAYS open
Leak Channel
Type of Channel Mediated Diffusion that is opened WHEN NEEDED
Gated Channel
Type of Facilitated Diffusion in which its opening CHANGES shape
Carrier Mediated Diffusion
Type of passive transport mechanism that tackles that movement of SOLUTE
Diffusion
Type of passive transport mechanism that tackles that movement of SOLVENT (water)
Osmosis
Type of a passive transport mechanism that is helped by the selectively permeable substance
Osmosis
2 locations where Osmosis can occur
- Lipid Bilayer
- Aquaporin
What is the SOLVENT in osmosis
Water
A type of transport mechanism that tackles the movement of solute AGAINST the concentration gradient
Active Transport
A type of transport mechanism that REQUIRES cellular energy
Active Transport
2 types of Active Transport
- Primary
- Secondary
What is used in Active Transport (transmembrane channels)
Ion Pumps
What happens in the Secondary Active Transport
High to low (produces energy) -> Low to high
What happens with ATP when active transport happens
(ATP = P & ADP)
2 types of Secondary Active Transport
- Antiport
- Symport/Symporter
Type of Secondary Active Transport which allows two substances move in the OPPOSITE direction
Antiport
Type of Secondary Active Transport which allows two substances move in the SAME direction
Symport/Symporter
Type of active transport which uses a TRANSPORT VESICLE (membranous sac found in the cytoplasm)
Vesicular Transport
2 types of Vesicular Transport
- Exocytosis
- Endocytosis
Type of Vesicular Transport where the cell transports a substance OUT the cell
Exocytosis
Type of Vesicular Transport where the cell transports a substance IN the cell
Endocytosis
3 types of Endocytosis
- Ph______
- Pi______
- Re______ Me______
- Phagocytosis
- Pinocytosis
- Receptor-Mediated Endocytosis
Type of endocytosis vesicular transport which refers to the entry of LARGE molecules
Phagocytosis
Type of endocytosis vesicular transport which refers to the entry of WATERY substances
Pinocytosis
Type of endocytosis vesicular transport which uses the CARBOHYDRATES attached in the lipid bilayer (LOCK & KEY)
Receptor-Mediated Endocytosis
