Homeostasis and Cell Transport

Front

What is the process called when molecules that are too large to be moved across a cell membrane are removed from the cell?

Back

Exocytosis.

Front

What is the term for the state when the concentration of water is equal inside and outside of a cell?

Back

Equilibrium.

Front

What happens to water in swollen gums when rinsed with warm salt water?

Back

The water in the gums moves out due to the high concentration of salt in the solution.

Front

What type of transport requires energy to move substances across a cell membrane?

Back

Active Transport.

Front

What is facilitated diffusion?

Back

A type of passive transport where molecules move across a cell membrane through protein channels without using energy.

Front

What is the main difference between passive and active transport?

Back

Passive transport does not require energy, while active transport does.

Front

What role do protein channels play in cell transport?

Back

They facilitate the movement of specific molecules across the cell membrane.

Front

What is osmosis?

Back

The diffusion of water across a selectively permeable membrane.

Front

What is the significance of concentration gradients in cell transport?

Back

Concentration gradients drive the movement of substances, with molecules moving from areas of higher concentration to lower concentration in passive transport.

Front

What is the effect of a hypertonic solution on a cell?

Back

A hypertonic solution causes water to leave the cell, leading to cell shrinkage.
