Study Guide 2 Chemistry of Life

What is a flexible covering that protects the inside of the cell from the environment outside the cell? Cell Membrane
What kind of membrane allows anything to pass through it? Permeable
What kind of membrane allows only some things to pass through them but not others. Semi-Permeable
What kind of membrane does not allow anything in or out? Non-Permeable
Is a cell's membrane permeable, non-permeable, or semi-permeable? Semi-Permeable
Things can move through a _____________ many ways depending on the size of the molecule or particle, the path taken through the membrane, and whether or not energy is used. Cell Membrane
_________________ is when the movement of substances across the cell membrane does not use the cell's energy. Passive Transport
__________________ is the movement of substances from an area of higher concentration to an area of lower concentration (from where there are more to where there are fewer.) Diffusion
Diffusion continues through a membrane until the concentration is the same on both sides of the membrane. This is called _______________. Equilibrium
______________ is the diffusion of water molecules only through a membrane. Osmosis
_______________ is the normal rigid state of fullness in a cell or blood vessel. Turgor
______________________ is when molecules pass through a cell membrane using special proteins called transport proteins. Facilitated Diffusion
_________________ is the movement of substances through a cell membrane only by using the cell's energy. Substances moving by ________________ are moving from areas of low concentration to areas of high concentration. Active Transport
_____________ is when a cell takes in a substance, that is too large to enter by diffusion or with the help of a transport protein, by surrounding it with the cell membrane. Endocytosis
________________ is when a cell's vesicles release their contents, which are too large to exit by diffusion or with the help of a transport protein outside of the cell. Exocytosis
