Cell Transport 1
What does the term "selectively permeable" mean?
only letting some things through
equilibrium
a form of diffusion that involves the movement of water across a cell membrane
osmosis
If the inside of cell contains 23% water and the outside of the cell contains 57% water, which direction will water move in order to reach equilibrium?
into the cell
Type of active transport that moves particles into a cell
endocytosis
Cell transport involves the movement of substances across the ____________
cell membrane
Diffusion is a type of ____________ transport
passive transport
Channel proteins that allow water to pass through the membrane at a very high rate are called ___________.
aquaporins
Solutions in which the solute percentage is greater outside the cell are known as _________
hypertonic
Pinocytosis moves what into the cell?
Water
The phospholipid heads that make up the plasma membrane are considered ____________ or "water loving".
hydrophilic
The form of energy that cells use during active transport
ATP
What type of transport requires energy.
active transport
A type of solution in which the solvent and solute percentages are the same inside and outside of the cell
isotonic
Process in which cells "eat" larger particles with the help of clathrin
phagocytosis
During Passive transport, substances move across the cell membrane from _______ concentration to ______ concentration.
Low
Diffusion across the plasma membrane with the help of membrane proteins is called _________________.
facilitated transport
During active transport, substances move from ________concentration to __________ concentration.
low
high
Solutions in which water must move into the cell to reach equilibrium are known as __________
hypotonic
These proteins bind to solutes and transport them across the plasma membrane.
carrier proteins
