100
What is the term for the Phospholipid bilayer that refers to it letting somethings pass through, but not everything.
Semi-permeable or Selectively permeable
100
The molecule that active transport uses to move large molecules against the concentration gradient [L] - [H]
ATP
100
Inside of cell : 80% salt, 20%water
Outside of cell: 50% salt, 50% water
What type of solution is the cell in?
Hypotonic
100
What is the difference between active and passive transport? (2 differences)
Active requires energy (ATP)/ Passive does not
and
Active goes against the concentration gradient [L] to [H]
Passive goes with the gradient [H] to [L]
200
What type of cell transport is represented by moving molecules from [H] to [L] with the concentration gradient?
Passive Transport
