Final answer:
Enzymes increase the rates of hydrolysis of triacylglycerols in the human body.
Step-by-step explanation:
The biomolecule that increases the rates of hydrolysis of triacylglycerols in the human body is C) enzymes.
Enzymes are protein molecules that act as catalysts in chemical reactions. Lipase is the specific enzyme responsible for hydrolyzing triacylglycerols into fatty acids and glycerol.
For example, Lipase produced by the pancreas is released into the small intestine during digestion to break down the triacylglycerols present in dietary fats into small molecules that can be absorbed by the body.
