Homeostasis and Cells

Front

How does a cell maintain homeostasis?

Back

Regulates what enters and leaves the cell.

Front

What is passive transport aided by transport proteins that does not require energy?

Back

Facilitated Diffusion.

Front

What is the process called when your body responds to cold by shivering and contracting blood vessels?

Back

Negative Feedback Loop.

Front

What is the ultimate cause of death related to cellular function?

Back

Loss of Homeostasis.

Front

What is homeostasis?

Back

The maintenance of a relatively stable internal environment, often incorporating feedback regulation.

Front

What is the role of the cell membrane in homeostasis?

Back

It acts as a protective barrier and regulates the movement of substances in and out of the cell.

Front

What is diffusion?

Back

The movement of molecules from an area of higher concentration to an area of lower concentration.

Front

What is osmosis?

Back

The diffusion of water across a selectively permeable membrane.

Front

What is the difference between active and passive transport?

Back

Active transport requires energy (ATP), while passive transport does not.

Front

What is a feedback loop?

Back

A process that uses the conditions of a system to regulate its function.
