Verified step by step guidance

Understand the definition of an enzyme: An enzyme is a protein that accelerates chemical reactions in biological systems without being consumed in the process. This is known as catalysis.

Review the term 'Biological catalyst': A biological catalyst refers to a substance, typically a protein or RNA, that speeds up biochemical reactions in living organisms. Enzymes fall under this category.

Analyze the term 'Structural lipid': Structural lipids are components of cell membranes, such as phospholipids and cholesterol, and are not involved in catalyzing reactions. This term does not describe an enzyme.

Evaluate the term 'Inorganic cofactor': Inorganic cofactors are non-protein molecules, such as metal ions (e.g., Mg²⁺ or Zn²⁺), that assist enzymes in their function. While they are important for enzyme activity, they are not enzymes themselves.

Consider the term 'Genetic polymer': Genetic polymers, such as DNA and RNA, store and transmit genetic information. They are not involved in catalyzing reactions, so this term does not describe an enzyme.
