CELLULAR TRANSPORT Flashcards
Give all types of PASSIVE TRANSPORT
Simple diffusion, facilitated diffusion, osmosis
Give all types of ACTIVE TRANSPORT
Primary active transport, secondary active transport, vesicular active transport
What solution if the cell stays the same shape? Shape?
ISOTONIC
What solution if the cell expands? Shape?
HYPOTONIC, TURGID shape
What solution is the cell shrinks? Shape?
HYPERTONIC, PLASMOLYSED shape
What happens to a cell if it is exposed to a hypertonic enviromnment?
Cell will shrink or osmosis will occur
What transport requires ATP (energy)?
ACTIVE TRANSPORT
Why does passive transport not need energy?
Because it moves along with the concentration gradient
It is responsible for molecular traffic
Vesicular transport
Movement of water from high to low concentration
Osmosis
Presence of channel and carrier proteins to help molecules pass
Facilitated diffusion
What transport moves from high to low concentration?
PASSIVE TRANSPORT
What transport moves from low to high concentration?
ACTIVE TRANSPORT
What type of active transport is the sodium-potassium pump?
Primary active transport
Transport of one substance is couples with the transport of another substance
Secondary active transport
