Hepatocytes are responsible for which of the following functions?

Hepatocytes are responsible for which of the following functions?

• A. Protein synthesis only
• B. Nerve impulse conduction
• C. Bone mineralization
• D. Protein synthesis, protein storage, transformation of carbohydrates, formation and secretion of bile, synthesis of cholesterol

Answer: (D)

Hepatocytes are versatile liver cells that handle synthesis, storage, and secretion to keep many body processes running. They synthesize a variety of proteins, such as albumin and clotting factors, and can store these products as needed for release into the bloodstream. They manage carbohydrate metabolism by converting excess glucose into glycogen for storage and by generating glucose when fuel is needed, effectively transforming carbohydrates. They form bile by producing and secreting bile acids and other components into bile canaliculi that drain into the bile ducts. They also synthesize cholesterol, which serves as a precursor for bile acids and lipoproteins. These combined activities—protein production and storage, carbohydrate transformation, bile formation, and cholesterol synthesis—are the hallmark functions of hepatocytes. Nerve impulse conduction is a function of neurons, and bone mineralization is carried out by osteoblasts.
