Macon: Homeostasis, Feedback, & Cell Transport

Front

What are the terms used to describe how the body reacts to stimuli?

Back

stimulus / response

Front

What is the purpose of a feedback loop in the body?

Back

To make sure the conditions in the body remain stable.

Front

Why is homeostasis crucial for living organisms?

Back

The survival of the cell, and therefore the organism, depends on it.

Front

What is the primary energy source required for active transport?

Back

ATP

Front

What is the structure of the cell membrane?

Back

The cell membrane has a double layer of phospholipids.

Front

Define homeostasis.

Back

Homeostasis is the process by which living organisms regulate their internal environment to maintain stable, constant conditions.

Front

What role do phospholipids play in the cell membrane?

Back

Phospholipids form the bilayer that makes up the cell membrane, providing structure and regulating the movement of substances in and out of the cell.

Front

What is the difference between passive and active transport?

Back

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

Front

What is a stimulus in the context of homeostasis?

Back

A stimulus is any change in the environment that can disrupt homeostasis and trigger a response.

Front

What is a response in the context of homeostasis?

Back

A response is the action taken by the body to counteract a stimulus and restore balance.
