How does the liver contribute to metabolism?

The liver plays a crucial role in metabolism primarily through its functions of detoxifying substances and processing nutrients. This organ is involved in the conversion of carbohydrates, fats, and proteins into usable energy sources. It processes nutrients absorbed from the digestive tract and helps maintain glucose levels in the bloodstream by either storing glucose as glycogen or converting glycogen back to glucose when needed.

Additionally, the liver detoxifies substances, such as drugs and alcohol, ensuring that harmful substances are broken down and eliminated from the body. By metabolizing these compounds, the liver helps regulate the overall chemical composition of the blood and maintain internal homeostasis. These metabolic functions are vital for energy production, nutrient distribution, and detoxification, underscoring the liver's significant contribution to overall metabolic processes in the body.
