Cell Transport Review (worksheet)
Terms in this set (26)
Transport protein that provides a tube-like opening in the plasma membrane
Is uses during active transport but not passive transport
Process by which a cell takes in material by forming a vacuole around it; The cell membrane forms around another substance, for example, how amoeba gets its food
Particle movement from an area of higher concentration to an area of lower concentration it is also the movement of substances through the cell membrane without the use of cellular energy
A form of passive transport that uses transport proteins
Process by which a cell expels wastes from a vacuole :a vacuole membrane fuses (becomes a part of) the cell membrane and the contents are released
Particle movement from an area of lower concentration to an area of higher concentration
The discussion of water through a cell membrane
used to help substances enter or exit the cell membrane
When energy is required to move materials through the cell membrane
When the molecules of one substance are spread evenly throughout another substance to become balanced
When molecules move from areas of high concentration to areas of low concentration
Difference in concentration of a molecule across two distinct areas, such as cell membrane
The process of maintaining a stable environment inside a cell or an entire organism
The ability to allow only certain molecules to cross the plasma membrane; Semipermeable
The feature of a cell membrane that allows only select molecules (ions and organic molecules) to enter and/or leave the cell; the ability to allow certain molecules to cross the plasma membrane; selectively permeable
In comparing two solutions of unequal solute concentration, the solution with the lower solute concentration. (the substance that has a lower concentration)
In comparing two solutions of unequal solute concentration, the solution with the higher solute concentration (the substance that has a higher concentration)
A substance that is dissolved in a solution.
A substance in which solutes dissolve
A mixture that forms when one substance dissolves another
Solution of equal solute concentration
The process of engulfing and breaking down pathogens and other unwanted substances
Type of vesicle transport that occurs when the plasma membrane folds inward to form a channel allowing dissolved substances to enter the cell.
Large molecules, food and other substances are packaged in membrane bound sacs called a vesicle and moved across the membrane
The movement of molecules from high concentration to low concentration, is a type of passive transport
