What type of biological molecule is lipase, and what does it degrade?

Lipase is classified as an enzyme, which is a type of biological molecule that catalyzes biochemical reactions. Specifically, lipase plays a crucial role in the digestive process by breaking down lipids, which are also known as fats. This degradation process involves hydrolyzing triglycerides into glycerol and free fatty acids, making them easier for the body to absorb and utilize for energy or other cellular functions.

This understanding establishes lipase's important function within the body's metabolic processes, particularly in fat digestion and overall energy balance. The other options do not accurately describe lipase or its functions; for example, hormones are signaling molecules and do not typically degrade substances like lipase does. Similarly, using 'protein' or 'carbohydrate' in this context misrepresents the nature of lipase and its specific role in the digestion of lipids.
