Homeostasis and Cellular Transport Flashcard

Front

How does the cell membrane contribute to homeostasis?

Back

By selectively allowing substances to enter and exit the cell.

Front

What is facilitated diffusion?

Back

Movement of molecules through a membrane protein without energy input.

Front

What is an example of active transport?

Back

Uptake of glucose in the intestines.

Front

What happens to a cell in a hypertonic solution?

Back

The cell will shrink as water leaves the cell.

Front

What is exocytosis?

Back

It involves the release of substances from the cell.

Front

Define homeostasis.

Back

The maintenance of a stable internal environment in an organism.

Front

What is the role of membrane proteins in cellular transport?

Back

They facilitate the movement of substances across the cell membrane.

Front

What is osmosis?

Back

The movement of water molecules across a selectively permeable membrane.

Front

What is the difference between passive and active transport?

Back

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

Front

What is a hypotonic solution?

Back

A solution with a lower concentration of solutes compared to the inside of the cell.
