Cellular transport study guide

What will happen to an animal cell placed in a saltwater solution?

the cell will shrink

This is the property of the plasma membrane that allows it to control what enters and leaves the cell.

Selective permeability

How do carrier proteins facilitate active transport?

Carrier proteins move substances from a low to high concentration.

This structure of the cell determines what can enter or exit the cell

Cell membrane

What compound assists in keeping the plasma membrane fluid?

Cholesterol

Diffusion occurs when there is a net movement of particles from an area of

High concentration to low concentration

Endocytosis

Into the cell

Exocytosis

Out of the cell

Predict how oxygen crosses the plasma membrane if the concentration of oxygen is lower inside the cell than it is outside the cell.

Oxygen enters the cell through the plasma membrane.

The diagram below shows a red blood cell in a beaker that contains a solution with a higher salt concentration than that inside the red blood cell. What will happen to the red blood cell in this environment

The red blood cell will shrink from losing water molecules

endocytosis

Which of the following is a form of passive transport?

facilitated diffusion
