Question: 1 / 830

Which enzyme does the liver secrete to help dissolve fats into solution?

Bile

The liver plays a crucial role in the digestion and absorption of fats by secreting bile. Bile is a digestive fluid that contains bile salts, which emulsify fats in the small intestine, breaking them down into smaller droplets. This process increases the surface area for enzymes to act, facilitating the digestion of fats and promoting their absorption into the bloodstream.

Insulin, on the other hand, is a hormone produced by the pancreas that regulates glucose levels in the blood. Glycogen is a form of stored glucose found mainly in the liver and muscle tissues and does not directly relate to fat digestion. Hematocrit refers to the proportion of blood volume that is occupied by red blood cells and is not involved in fat emulsification or digestion. Thus, bile is the correct choice for its specific function in fat metabolism.
