Definition of Homeostasis

Homeostasis is the process by which an organism maintains stable internal conditions, such as temperature and pH, despite changes in its external environment. Homeostasis is essential for optimal functioning and survival.

How Metabolism Supports Homeostasis

Metabolism and homeostasis work together to keep our bodies balanced and healthy. Metabolism is all the chemical reactions in the body that turn food into energy and build or repair cells. This energy powers all the body’s activities, like moving, breathing, and even thinking.

Homeostasis is the process of keeping internal conditions, like body temperature, blood sugar, and pH levels, stable even when things around us change. Metabolism supports homeostasis by providing the energy needed to maintain these stable conditions. For example:

  • When it’s cold, metabolism speeds up to produce extra heat, helping to keep our body temperature steady.
  • After eating, metabolism works to break down food and adjust blood sugar levels, keeping them from getting too high or too low.

By constantly adjusting and providing energy, metabolism helps the body stay balanced and respond to changes, which is what homeostasis is all about.
