Front

What property of the plasma membrane allows it to control the movement of substances into and out of the cell?

Back

Selective permeability

Front

What are the proteins called that help move substances across the plasma membrane?

Back

Transport proteins

Front

What is the difference between passive transport and active transport?

Back

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

Front

What is the role of the plasma membrane in cellular homeostasis?

Back

The plasma membrane regulates the internal environment of the cell by controlling the entry and exit of substances.

What is facilitated diffusion?

Back

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

Front

What is the significance of selective permeability in cells?

Back

Selective permeability allows cells to maintain a stable internal environment by controlling which substances can enter or exit.

How do transport proteins contribute to selective permeability?

Back

Transport proteins facilitate the movement of specific substances across the plasma membrane, allowing the cell to selectively absorb nutrients and expel waste.
