What vital substances does the liver store?

  1. Amino acids and proteins

  2. Water and minerals

  3. Vitamins and glucose

  4. Hormones and enzymes

The correct answer is: Vitamins and glucose

The liver plays a crucial role in storing vital substances that are essential for various bodily functions. Among its many functions, one of the liver's primary roles is the storage of vitamins, particularly fat-soluble vitamins such as A, D, E, and K. Additionally, the liver stores glucose in the form of glycogen, which can be converted back to glucose when the body requires it for energy. This storage is vital for maintaining blood sugar levels and providing energy during periods of fasting or increased demand. The presence of vitamins and glucose in the liver highlights its importance not only in nutrient storage but also in metabolic regulation. The effectiveness of the liver in managing these substances contributes significantly to overall health and the body's ability to respond to changing energy needs.
