passive
Is osmotic pressure active or passive
passive
Does passive transport require energy?
little to none
Which way in passive transport does the substance move along the concentration gradient?
down
In passive transport does a substance move from high to low concentration?
yes
Does active transport require energy
yes
In active transport does a substance move from low to high concentration?
yes
What type of energy does passive transport use?
Adenosine triphosphate (ATP)
Which way in active transport does the substance move along the concentration gradient?
against
What is diffusion
the process by which molecules move from a position of high concentration to a position of lower concentration
What physical variables is diffusion heavily dependent on
temperature, size of the molecule, and type of medium
