Cell Transport

Front

What is osmosis?

Back

Osmosis is a form of passive transport where water molecules move across a semipermeable membrane from an area of low solute concentration to an area of high solute concentration.

Front

What type of transport occurs when solutes move with the concentration gradient?

Back

Passive Transport.

Front

What is the main characteristic of active transport?

Back

Active transport requires energy (ATP) to move molecules against their concentration gradient.

Front

What is facilitated diffusion?

Back

Facilitated diffusion is the process by which molecules move across the cell membrane from an area of high concentration to an area of low concentration through a carrier protein.

Front

What is endocytosis?

Back

Endocytosis is an active transport process where cells engulf substances from the outside environment, bringing them into the cell.

Front

What is the difference between passive and active transport?

Back

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

Front

What role do carrier proteins play in cell transport?

Back

Carrier proteins assist in the facilitated diffusion of molecules across the cell membrane, allowing specific substances to enter or exit the cell.

Front

What is diffusion?

Back

Diffusion is the movement of molecules from an area of high concentration to an area of low concentration until equilibrium is reached.

Front

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

Back

The concentration gradient is the driving force for passive transport, as substances naturally move from areas of high concentration to areas of low concentration.

Front

What is the function of ATP in active transport?

Back

ATP provides the energy required for active transport processes to move molecules against their concentration gradient.
