Cellular Transport

Front

What is the process called that involves the movement of water across a selectively permeable membrane?

Back

Osmosis

What structure in the cell is responsible for controlling the entry and exit of substances?

Back

Cell Membrane

Front

What term describes the state when the concentration of solutes is equal inside and outside of a cell?

Back

Equilibrium

Front

Define diffusion in the context of cellular transport.

Back

Diffusion is the movement of particles from an area of high concentration to an area of low concentration.

Front

In which direction do particles move during diffusion?

Back

From a region of high concentration to a region of low concentration.

Front

What is the difference between passive transport and active transport?

Back

Passive transport does not require energy and moves substances down their concentration gradient, while active transport requires energy to move substances against their concentration gradient.

Front

What is facilitated diffusion?

Back

Facilitated diffusion is a type of passive transport that uses transport proteins to help move substances across the cell membrane.

Front

What role do channel proteins play in cellular transport?

Back

Channel proteins provide a passageway for specific molecules to cross the cell membrane.

Front

What is the significance of the concentration gradient in diffusion?

Back

The concentration gradient drives the movement of particles during diffusion, with substances moving from areas of higher concentration to areas of lower concentration.

Front

What happens to a cell placed in a hypertonic solution?

Back

The cell will lose water and shrink due to osmosis.
