Check all statements that are functions of the liver. Check All That Apply
A. Production of bile.
Production of bile: the liver synthesizes and secretes bile (stored in the gallbladder).
B. Detoxification of toxins
Detoxification of toxins: the liver metabolizes and detoxifies many endogenous and exogenous compounds.
C. Production of glycogen
Production of glycogen: the liver synthesizes and stores glycogen (glycogenesis) to regulate blood glucose.
D. Digestion of nucleic acids
Digestion of nucleic acids: nucleic acid digestion is performed by pancreatic and intestinal enzymes in the small intestine, not by the liver.

Which of the following is needed to digest fats?
A. Pepsin or trypsin and peptidases
Pepsin or trypsin and peptidases: these are protein digesting enzymes, not primary fat digesters.
B. Amylase and disaccharidases
Amylase and disaccharidases: these digest carbohydrates, not fats.
C. Lipase
Lipase: lipase (plus bile for emulsification) is required to chemically digest fats into fatty acids and glycerol.
D. Amylase and pepsin
Amylase and pepsin: amylase digests starch and pepsin digests proteins; neither is the principal fat-digesting enzyme.
