Cell Transport – Quiz – Flashcards

Requires the input of energy to move molecules from a low concentration to a high concentration

The movement of relatively large quanities of material into or out of a cell at one time (does not use energy)

The use of proteins in a cell membrane to move molecule from a low concentration on one side to a high concentration on the other.

The movement of relatively large quantities of material into a cell at one time.

The movement of relatively large quantities of material out of a cell at one time.

The movement of molecules from a high concentration to a low concentration, without the input of energy

The movement of water from a high concentration to a low concentration, across a semi-permeable membrane without the input of energy.

Scenario: Salt is poured onto a leech causing it to release its bite from the victim.

Scenario: Cell in the human body take cholesterol particles in by endocytosis.

Scenario: Cells in the human body have proteins that work to maintain negatively charged particles inside of the cell while keeping positively charged particles outside of the cell. This goes against concentration gradient.

Scenario: Ink that was released into the water by a squid moments later became unnoticeable.

ablity of particle to pass through a membrane

The concentration of solutes in the solution is lower than inside the cell.

The concentration of solutes in the solution is higher than inside the cell.

The concentration of solutes inside the cell is the same as outside the cell.
