Active and Passive Transport

Front

What is the process that gets rid of wastes from a cell?

Back

Exocytosis is the process that gets rid of wastes from a cell.

Front

In which type of solution will water move into the cell, potentially causing it to burst?

Back

In a Hypotonic solution, water moves into the cell, which can cause it to burst.

Front

What is a solution with a higher concentration of solutes compared to another solution called?

Back

A solution with a higher concentration of solutes is called Hypertonic.

Front

What is the movement of molecules against a concentration gradient called?

Back

The movement of molecules against a concentration gradient is called Active Transport.

Front

In facilitated diffusion, how do molecules move?

Back

In facilitated diffusion, molecules move down a concentration gradient.

Front

What is the term for the movement of water across a semipermeable membrane?

Back

Osmosis is the term for the movement of water across a semipermeable membrane.

Front

What is the difference between active transport and passive transport?

Back

Active transport requires energy to move molecules against a concentration gradient, while passive transport does not require energy and moves molecules down a concentration gradient.

Front

What is diffusion?

Back

Diffusion is the process by which molecules spread from areas of high concentration to areas of low concentration.

Front

What happens to a cell in a hypertonic solution?

Back

In a hypertonic solution, water moves out of the cell, causing it to shrink.

Front

What is isotonic solution?

Back

An isotonic solution has the same concentration of solutes as another solution, resulting in no net movement of water.
