Module 07 - Homeostasis Review

Front

What is homeostasis?

Back

Homeostasis is the process by which living organisms maintain a stable internal environment despite changes in external conditions.

Front

What is a negative feedback loop?

Back

A negative feedback loop is a mechanism that counteracts a change in a system, helping to maintain stability by reducing the output or activity when a certain level is reached.

Front

What is the role of ATP in cellular respiration?

Back

ATP (adenosine triphosphate) is the energy currency of the cell, produced during cellular respiration to provide energy for various cellular processes.

Front

What happens when blood oxygen levels are low?

Back

The body responds by increasing the breathing rate to enhance oxygen intake.

Front

What are ectotherms?

Back

Ectotherms are animals whose body temperature regulation depends on external sources, such as sunlight or heated surfaces.

Front

What is the significance of maintaining homeostasis?

Back

Maintaining homeostasis is crucial for survival, as failure to do so can lead to lack of internal balance, metabolic difficulties, and even death.

Front

What is an example of a homeostatic response?

Back

An example of a homeostatic response is sweating to cool down the body when it becomes overheated.

Front

How does the body respond to high blood sugar levels?

Back

The body responds to high blood sugar levels by releasing insulin, which helps cells absorb glucose.

Front

What is the difference between endotherms and ectotherms?

Back

Endotherms regulate their body temperature internally (e.g., mammals), while ectotherms rely on external environmental conditions.

Front

What is the role of feedback mechanisms in homeostasis?

Back

Feedback mechanisms, such as negative feedback loops, help regulate physiological processes to maintain stability in the body.
