Cellular Transport Part 1

Front

What is the direction of molecule movement during active transport?

Back

Against the concentration gradient.

Front

What type of transport protein allows only water to pass through the membrane?

Back

Aquaporin.

Front

What process do plant root cells use to take in mineral ions from the soil?

Back

Active Transport.

Front

How is concentration defined in terms of solute and solution?

Back

The amount of solute in a specific amount of solution, measured in grams per liter.

Front

What is diffusion?

Back

The movement of particles from high to low concentrations.

Front

What is the primary difference between passive and active transport?

Back

Passive transport does not require energy, while active transport requires energy to move molecules against their concentration gradient.

Front

What is osmosis?

Back

The diffusion of water across a selectively permeable membrane.

Front

What role do carrier proteins play in cellular transport?

Back

Carrier proteins facilitate the movement of specific molecules across the cell membrane.

Front

What is the significance of the concentration gradient in cellular transport?

Back

It determines the direction in which molecules will move, from high to low concentration in passive transport.

Front

What is facilitated diffusion?

Back

A type of passive transport that uses transport proteins to move molecules across the membrane without energy.
