Active Transport, Cell Membrane, and Homeostasis

Front

What does it mean that the cell membrane is selectively permeable?

Back

It means that certain things can enter while others cannot.

Front

What type of cell transport is represented by the process of engulfing materials into the cell?

Back

Endocytosis.

Front

What is required for active transport?

Back

ATP (energy) is required.

Front

In which direction does active transport move materials?

Back

It moves materials from low to high concentration, against the concentration gradient.

Front

What is the definition of active transport?

Back

Moving particles while using a cell's energy.

Front

What do all living cells have in common?

Back

All living cells have a cell membrane.

Front

What is the primary function of the cell membrane?

Back

To protect the cell and regulate what enters and leaves.

Front

What is osmosis?

Back

The movement of water across a selectively permeable membrane.

Front

What is diffusion?

Back

The movement of particles from an area of high concentration to an area of low concentration.

Front

What is the difference between passive transport and active transport?

Back

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