The correct pairs related to the two types of lipids are "fats" and "oils."
The two main types of lipids are:
Fats (triglycerides): These are lipids that are solid at room temperature. Fats are composed of three fatty acid molecules linked to a glycerol molecule.
Oils (also triglycerides): Oils are lipids that are liquid at room temperature. They are also composed of three fatty acid molecules linked to a glycerol molecule.
In the given options, "enzyme" and "nucleic acid" are not types of lipids. Enzymes are proteins, and nucleic acids (such as DNA and RNA) are a different class of biomolecules. It's important to note that proteins are also a distinct category of biomolecules, different from lipids.
So, the correct pairs related to the two types of lipids are "fats" and "oils."
