Verified step by step guidance

Understand the concept of homeostasis: Homeostasis is the body's ability to maintain a stable internal environment despite changes in external conditions. It involves various physiological processes to regulate factors like temperature, pH, and energy levels.

Identify the role of glycogen: Glycogen is a stored form of glucose, primarily found in the liver and muscles. It serves as a reserve of energy that can be quickly mobilized to maintain blood sugar levels during fasting or increased energy demands, thus contributing to homeostasis.

Consider the role of urea: Urea is a waste product formed in the liver from the breakdown of proteins. It is excreted by the kidneys and does not play a role in storing energy or maintaining homeostasis.

Evaluate the function of carbon dioxide: Carbon dioxide is a byproduct of cellular respiration and is expelled from the body through the respiratory system. It is not stored for homeostasis but is regulated to maintain acid-base balance.

Assess the significance of lactic acid: Lactic acid is produced during anaerobic respiration when oxygen levels are low. It is not stored for homeostasis but is temporarily accumulated and later converted back to pyruvate or glucose when oxygen becomes available.
