1.13 Movement IN/OUT of cell

What is needed for endycytosis, exocytosis, and active transport?

• difussion

• facilitated difussion

• osmosis

• filtration

• energy

If you drop red dyes in a solution of water, when all the water is red the solution has reached????

• a concentration gradient

• diffusional equilibrium

• homeostasis

• a condition of active transport

Oxygen concentration is higher

• inside the cell

• outside the cell

• the concentration is the same due to diffusional equilibrium

• When your metabolism is high

In facilitated diffusion what must happen to assist a glucose molecule to to cross the membrane?

• use of a carrier molecule

• assistance by a hormone

• changing the shape of the molecule

• all of these

What causes osmotic pressure to be high?

• a permeable membrane

• an impermeable membrane

• high concentration of impermeant solute particles in a solution

• a solution that is hypotonic

What would cause a cell to get larger?

• solution is hypertonic

• solution is hypotonic

• solution is at equilibrium

• all of these

Molecular diffusion is different than filtration due to

• no pattern in the movement of molecules

• hydrostatic pressure

• osmosis

• the separation of solids from water

What process assist in keeping your blood clean?

• filtration

• osmosis

• hydrostatic pressure

• uniration

What is needed for particles to move from an area of low concentration to an area of high concentration

• energy

• ATP

• cellular metabolism

• all of these

What is needed for the process of endocytosis and exocytosis to move thing into and out to the cell

• ADP

• "pumps"

• carrier molecules

• vesicles
