Question

How do cells use energy to maintain homeostasis

Answer 1

Cells use energy, specifically ATP, to power processes that maintain homeostasis. This includes regulating ion and molecule concentration, temperature, pH, and other internal conditions. Examples include active transport and thermoregulation.

Step-by-step explanation:

Cells use energy to maintain homeostasis by various mechanisms. One of the main ways is through the production and use of ATP (adenosine triphosphate), which is the energy currency of cells. ATP is generated through cellular respiration, where glucose is broken down to release energy that can be utilized by the cell for various functions, including maintaining homeostasis. For example, ATP is used to power active transport processes that help regulate the concentration of ions and molecules inside and outside the cell, maintaining the appropriate balance for cellular functions.

Additionally, cells use energy to regulate temperature, pH, and concentrations of chemicals within the body. This can be seen in processes such as thermoregulation, where organisms adjust their body temperature to maintain homeostasis. For instance, sweating in humans helps to cool down the body in hot conditions, while shivering helps generate heat in cold conditions.

In summary, cells use energy in the form of ATP to power various processes that help maintain homeostasis, such as active transport and thermoregulation.

Answer 2

Step-by-step explanation:

The water wants to flow from the higher concentration, which is outside of the cell, to the lower concentration, which is inside of the cell. The cell membrane helps to regulate and slow down the flow of water into the cell. This is yet another way that the cell membrane helps maintain homeostasis.
